I concur!  We've been adding ugly nasty hacks to druntime, or writing code in circumlocutous ways, for far too long now, all because certain basic traits happen to be in std.traits and it's verboten to import Phobos from druntime.  It's time to revisit that decision.  The more complex traits should remain in Phobos in order not to complicate druntime too much, but the basic ones needed also in druntime should moved into druntime, instead of copy-pasta or roll-your-own in druntime.

It's amazing how careful choice of punctuation can leave you hanging:

Great! So, who's gonna do it?
I'm already overloaded with these sorts of refactors >_<
