Phobos PR: `call` vs. `bindTo`

[H. S. Teoh via Digitalmars-d]

There are currently two Phobos PR's that implement essentially the same
functionality, but in slightly different ways:

	https://github.com/D-Programming-Language/phobos/pull/1255
	https://github.com/D-Programming-Language/phobos/pull/2343

>From the discussion on Github, it seems to me that we should only
introduce one new function rather than two similar but
not-quite-the-same functions. Since the discussion seems stuck on
Github, I thought I should bring it here to the larger community to see
if we can reach a consensus (who am I kidding... but one can hope :-P)
on:

(1) What name to use (bring on the bikeshed rainbow)
(2) Exactly what functionality should be included.
(3) Which PR to merge.
