If you could remind me again which those objections were specifically?
IIRC the only one was "no language extension in GCC", despite that
extension being implemented in most other real world compilers, and the
completely trivial specification of it.

Pardon me?  If I understand correctly you propose to add something like
C++ destructors (or a subset, whatever that means) to C to not have to add
try/finally?  Surely you are kidding, aren't you?  You must be.  Compared
with defining try/finally, defining that extension would be _major_ work.
IMHO those are strange ideas to just not have to do try/finally, sorry.


Ciao,
