This ought to return false because the types are different.
So in short, what is the flaw in just testing the way two function objects are represented internally
It would be surprising, because nothing else works that way.
I agree it might be surprising from an implementation standpoint. But are there examples of functors such that equality implemented this way would return a surprising result? If the result isn't surprising, then I don't think the implementation should matter much, as long as it relies only on standards conformant language aspects. Again I could just be overlooking something due to lack of understanding of the implementation details of boost::function<>, but at least on the surface it seems to me that the behavior would always produce expected results.
