std.traits and tango.core.Traits have a number of superficial 
differences, such as ReturnType versus ReturnTypeOf, ParameterTypeTuple 
versus ParameterTupleOf, and so forth. This has been a source of 
annoyance for me in the past, until I decided to give up on it and just 
go with Tango. (I think the other part that decided it was Phobos's 
Variant type.)

tango.core.Traits has more than Phobos1's std.traits, but Phobos2 has 
most of that functionality. Is there any reason not to backport it?
