If we really need Rebindable in druntime, then we can simply move it to an 
appropriate place in druntime and alias std.typecons.Rebindable to it.

core.time exists specifically because druntime needed some of the datetime stuff 
(most particularly the duration stuff). Otherwise, everything in it would be in 
std.datetime (where it was when originally proposed).

We can do the same with other constructs if we really need to. We just don't 
want to be moving them to druntime if we don't actually need to.
