Looking at the online documentation, it says:
__traits "are extensions to the language to enable programs, at compile time, to get at information internal to the compiler."
std.traits are "Templates which extract information about types and symbols at compile time.
Do they both basically do the same thing? They both have isIntegral, but there is a lot of functionality that they don't share.
I guess one naive question would be, why not just have all the __traits functionality rolled into std.traits? Or vice versa?
