Sorry, did your remark above suggest I don't know what an lvalue is?

That seemed like the obvious explanation for the incorrect information
you gave.  Did you post it /knowing/ what other kinds of things are
lvalues in C just to confuse people?

I merely said that LHSs of assigments fall into these categories:

Yes, that incorrect explanation.

Clearly I mean VALID LHSs, otherwise they wouldn't be LHSs of assignments!

I've since learnt about a couple of other possible categories; one is with
compound literals like '(int){42} = 0'.

Along with (a) _Generic expressions (where the selected arm is an
lvalue) and (b) expressions of the form X->m.

(I don't count (A), ((A)) etc as a
separate category; come on!)

Don't give me "come on!".  I was counting forms in the same way that you
were when I said I could think of three more.  I was not counting
parentheses.

The other is 'X.m' but when .m is a bitfield;

What makes X.m = Y, where m is a bitfield, an extra category?  It fits
the X.m = Y pattern perfectly well.

although this has the same
same syntax as above, internally it's somewhat different.

Your categories were syntactic.  You were describing forms.

(My C compiler
treats bitfields as ordinary members.)

I acknowledge that allowing 'F().m = Y' is wrong;

Thank you.

I might get around to
fixing it one day.
