The documentation is misleading, then:
The object argument can be a reference or pointer to the object, the
BLL supports both cases with a uniform interface:
bool A::foo(int) const;
find_if(ints.begin(), ints.end(), bind(&A::foo, a, _1));
find_if(ints.begin(), ints.end(), bind(&A::foo, &a, _1));

Yuck. Oh well, guess that's what I'll do. Are there any plans to
add direct support for smart pointers?
