Can it be moved to <utility>? I imagine there's already a fair amount
of C++0x code out there which depends on it, and likely the popular
implementations haven't yet removed it so the impact is yet unknown.

I would also vote to bring it back, if it's really removed. It's one of the
most basic *and* (imho) useful metafunction and it's missing? That would be
odd.
