Re: [Boost-users] Equality comparison of boost::function<>

But what about this?

less<int> f; function g = f; function h = f;

Checking based on address won't be able to tell that g == h, since copies of f will be taken for lifetime reasons.

That's not a problem at all. Boost.function holds its content by copy. The real issue is that function objects aren't equality comparable. Function pointers are, but not function objects.
