http://www.open-std.org/JTC1/sc22/wg21/docs/papers/2007/n2270.html notes:

 Various people have suggested deprecating the following features:
   * std::mem_fun, std::mem_fun_ref, and their associated classes
(Again, since std::mem_fn has all the same functionality but is more
convenient and uniform).
   * std::ptr_fun and its associated classes

These things are not deprecated in N2800, so presumably reasons were
found not to deprecate them.  Does anybody know what they are?

Thanks,

Scott
