Hi,

This would be fairly weird semantic. If the finally is formulated as a
destructor of an anonymous object (like Richard suggested) then it should
be run after the __try block exits, in _whichever_ way it does so. This
also makes much more sense to me. I wouldn't like to have to write:
__try {
if (bla())
return;
}
__finally {
cleanup();
}
cleanup();
just because the __finally block isn't executed sometimes. It also makes
the rule quite easy. The finally is executed after the try block, no
matter what.
Ciao,
Michael.
