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

2009/8/8 Christopher Jefferson <chris@bubblescope.net>:

That sounds very unnecessary. Surely it would be sufficient, and what most people would expect, to check if the two function objects point to the same function (in the sense of location in memory), as opposed to logically equivalent functions?

But what about this? less<int> f; function<bool(int,int)> g = f; function<bool(int,int)> 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.
