Sorry, I was busy.  I see KT as given a good summary (though I was not
counting forms in parentheses).

You have implemented a C compiler.  The wind-up I sensed was your giving
out misinformation, but I'll just have to take your word for it that
you've been arguing about assignments without know what constitutes an
lvalue expression.

But when I didn't answer soon enough, surely you could have just looked
in any good C reference to find all the expression forms that are
lvalues.

f().m where f returns a struct.
