std.bind

[Andrei Alexandrescu]

It was rightly suggested that std.bind either gets some love or gets 
removed from Phobos. Walter convinced me that delegates are a flexible 
alternative to std.bind's arcane notation.

One possible line of work would be to extend std.functional.curry, which 
is a bit limited right now.

At any rate, I'm considering deprecating std.bind. Its design and code 
look dated by today's standards (we've been a long way!) and hardly 
anyone seems to be using it. Should we deprecate it?
