I think that had have been suggested.

I was avoiding it (I hack on too many versions of GCC already!), but it's becoming necessary...

I'm glad to see your implementation of decltype is more complete than what I had 2-3 years ago. However, the manling issue still needs to be resolved. There is an open PR for that -- involving typeof.

Looks like there are a couple PRs against typeof for similar issues. With decltype, I chose to skip the expression entirely, because mangling arbitrary expressions is a mess that I am eager to avoid. When they reopen the C++ ABI discussions for C++0x, that'll be the time to deal with this mangling issue...

Cheers, Doug
