The possibility of splitting out all traits (not just those in std.traits) 
into a separate module hierarchy has been brought up and discussed to some 
extent, but we haven't really decided on anything yet. But putting all of the 
traits in a separate hierarchy would allow us to hugely reduce the dependency 
hierarchy, because in a lot of cases, they're the reason that a module pulls 
in as many dependencies as it does, and when the dependency is for a trait 
used in a template constraint, the import can't be localized.

So, if we want to reduce module interdependence, we really probably should 
look at splitting out the traits as well as possibly some key items that we 
know most everything ends up needing (like the range primitives for arrays or 
the formatting and conversion stuff).
