Function and shared_ptr use the safe_bool idiom, and I'm sure it's in
other places as well (Optional, perhaps?). It's the same situation as with
enable_if: implementations abound in Boost, so the library seeks to unify
those implementations. The differences here are that (1) the
functionality's already been in CVS for 6 months ready for users to apply
and (2) we don't seem to have a consensus that bool_testable is the right
way to go. #1's somewhat irrelevant, because the fast-track review did not
exist when it was added. #2 seems like the purpose of the review.
