I'm glad you're looking for duplication.  Nice work.  It's complicated, I'm sure, by the various names folks may choose for the same trait, though no doubt prefixes like "is_" help.

Have you looked for compound traits in other libraries that could be added to TypeTraits for convenience?  That is, if it is very common to combine certain traits, then a single trait that captures the compound would simplify a good deal of code.
