I am absolutely opposed to this idea. The order of includes should
not matter. If anything, functional.hpp would include mem_fun.hpp.
However that includes a lot of extra baggage, and also your mem_fun1_t
replacement doesn't use call_traits so I suspect suffers from the
Of course that can be fixed, but then we have compiler compatibility
issues, compile time issus and anyway I still have to question the need for
a new mem_fun. It seems that if anything, it should be an implementation
detail. As far as I can make out
mem_fun( &X::foo )( x, 123 );
bind( &X::foo, _1, _2 )( x, 123 )
are equivalent, so why not only allow the latter form? And I repeat,
given that the latter doesn't actually bind anything, why call it bind?
