Hi Dhruv! Sorry for the delay.

Ack! Not another one! We've already got two!

I think this might be an interesting place to start with this patch.

I think it makes more sense to make include/tr1/type_traits,
tr1/type_compare, tr1/type_transform. These includes would be modeled on
the proposed files in TR1.  Also remove all the various other traits
bits we have now: bits/type_traits.h, bits/cpp_type_traits.h.

Matt can point you at the spec, but I think the most recent version of
this should be in N1518.
