I keep getting lots of these:

Would it be possible for the mem_fn header to #pragma push a warning disabler for MSVC?
These warnings are probably a sign that the data member mem_fn/bind overload is being picked instead of the correct member function overload. They usually indicate a bug in your code. For example, you've used bind(&X::f, _1) but &X::f doesn't take zero arguments.
Wow, so they are! I was getting other errors, and when I fixed those the warnings disappeared too.
Incidentally, the errors I get when I misuse bind somehow (which happens frequently!) are *really* bad at telling me what I've done wrong. Any chance of improving those?
They are, no question about it. It's mostly a question of supporting MSVC 6-class compilers, and partially a question of dependencies (type_traits, for example). I suspect I can do much better in a hypothetical 100% TR1 bind that only targets 100% conforming compilers (and can freely use other TR1 libraries). But what would the point be? Isn't Lambda supposed to fill that role? ;-)
