Still not a complete list. :-)

If I am instrument rated and my aircraft is fully equipped for
instrument flight, and I start out a flight with a VFR flight plan,
and it gets foggy enough that I'm below minimums, is there a way to
switch to IFR in flight,

Yes. It's called a pop-up clearance.

or do I have to have filed IFR from the beginning?

No.

If it's possible in flight, how does it work?

Just ask ATC for a clearance. If they aren't too busy they will just
give you one. If they are busy you will need to contact flight service
by radio to file an IFR flight plan, then get back in touch with ATC to
activate it.

Landing somewhere first is also an option.

Is it possible to later switch back again?

Yes, you can switch from IFR to VFR at any time by simply telling ATC
that you are "canceling IFR."

I ask because it seems like it might be practical to start out as VFR
but still have the option of going IFR if the weather turns
unexpectedly poor (at least in terms of visibility or clouds). At the
same time, filing IFR for the whole flight just because part of it
_might_ be in IMC seems like it could be overkill.

Why? People fly IFR in VFR conditions all the time.

This of course assumes that a pilot and aircraft are ready and able to
handle IMC if they encounter it.

It's much better to be IFR the whole way if there's any chance of
encountering instrument conditions anywhere on the flight.

Do I have to work out a whole list of waypoints and stuff to give to
them? Can I just ask for IFR clearance to my destination (or to some
specific point where I expect to find VMC again), without specifying
waypoints or altitudes?

Usually I have a VFR flight plan which in fact does include waypoints,
because I've worked something out with a chart beforehand, but not
always. If I've filed a VFR flight plan that mentions way points, can
I refer to it when asking ATC for IFR clearance? In other words, just
convert part of the VFR flight plan to an IFR flight plan?

Yes, but if I can't see anything out the window, this is not without
risk (mainly from conflicting traffic, even if I have instruments that
allow me to land in poor visibility).

Yes, you can switch from IFR to VFR at any time by simply telling ATC
that you are "canceling IFR."

Do I get in trouble if I file VFR, encounter IMC, and have to ask for
IFR clearance as a result? I know I'm not supposed to take off in
IMC, but it seems like on a trip of substantial length, it's hard to
guarantee that it will all be fair weather, especially in some regions
of the world (the area around Seattle seems very pretty, although it
also seems that one can rarely _see_ the area around Seattle).

Why? People fly IFR in VFR conditions all the time.

I recall reading that the vast majority of private pilots (80%?) are
not instrument rated, and that many accidents involving small planes
occur when non-IR pilots fly into IMC and become disoriented. So I
assume that it's rare for the pilot of a small plane to fly IFR
"unofficially" while under VFR. It sounds like a lot of them have no
idea how to do it.

Because ... ?

It is possible to read many things that are not true - particularly if you
hang out in places like this!!

The number of US private pilots who are instrument rated is much better than
this - which unfortunately does not preclude them from becoming disoriented
in IMC. The subject of instrument flight and training is very interesting,
but relatively complex, involving matters of human factors, training
methods, regulations and their interpretation, currency requirements and
their interpretation and usefuleness and I could go on - All of these
considerations put the subject out of reasonable bounds for those who have
no genuine interest in learning.

I don't remember where I read it.

Does that include private pilots who fly only small GA aircraft, or is
it _all_ private pilots (including commercial airline pilots)?

It doesn't matter what the statistics are like in the real world. In your
simulator, the program will not change.

Nope, they (actually their computer) will figure that out for you.

Yep.

Nope, ATC has no access to VFR flight plans.

Yes, but if I can't see anything out the window, this is not without

If you can't see anything out the window and you are VFR then you're
already screwed. Time to declare an emergency.

Not unless you actually enter IMC without an IFR clearance.

I know I'm not supposed to take off in
IMC, but it seems like on a trip of substantial length, it's hard to
guarantee that it will all be fair weather, especially in some regions
of the world (the area around Seattle seems very pretty, although it
also seems that one can rarely _see_ the area around Seattle).

That's why having a plan B is always advisable.

I have no idea what you mean by 'flying IFR "unofficially"'. It's true
that many people don't have instrument ratings. Those people have fewer
options when flying cross-country.

It's much better to be IFR the whole way if there's any chance of
encountering instrument conditions anywhere on the flight.

I'll leave that as an exercise for you to figure out.

Well, if you are equipped for instrument flight and rated for it and
there isn't too much traffic, I wouldn't call it an emergency,
although you do need to get flight separation services or get back to
VMC as quickly as possible.

I have no idea what you mean by 'flying IFR "unofficially"'.

Flying using instruments even though you haven't filed an instrument
flight plan. For example, my habit of flying with a GPS or by
following VORs rather than looking for landmarks out the window.

Then you are missing something very fundamental: there is more to IFR
flight than simply flying by reference to instruments. It is also
flying according to a much more rigidly planned and stylized repertoire
of routes and maneuvers designed to keep you from hitting not only other
airplanes but also (and more importantly) terrain. That is why even
instrument-rated pilots flying instrument-equipped planes die on a
regular basis as a result of VFR flight into IMC.

although you do need to get flight separation services or get back to
VMC as quickly as possible.

That takes time. How are you going to keep from hitting things in the
meantime?

Flying using instruments is NOT the same thing as flying IFR.

Oh brother. Not knowing anything about real IFR, the FARs, ATC
procedures, and the inherent safety problem (until you eventually
get your requested IFR clearance), your dogmatic statement like
the above is absurd.
