Akim,
Excuse me for reposting this - I just realized that I didn't sent this
message to the mailing list.
And it's normal: since you are looking deep in the stack, Bison cannot
figure out (in the general case) what the kind of symbol is there. So
it can't guess the field of the union it needs to use to decode the
semantic value.
A situation where you declare a type and still get a "has no declared
type" error didn't seem normal to me, that's why I had to dig into the
source code and post here.
You're asking for completely new developments here. There is nothing in
the internals to have this work (yet it would be nice if it could).
I understand. But maybe this should be documented somewhere, or maybe
bison should issue some special message in this case? Otherwise this might
confuse some inexperienced users (like myself). I would provide a patch
for a special message, but that would be a trivial one and I don't think I
would save you a lot of work.
Best,
Sandy
