This makes (at least) UnsignedTypeOf unused in Phobos, and it's 
undocumented but public. There are LREFs in the std.traits docs 
under the SomethingTypeOf section - none of these links go 
anywhere AFAICT. Presumably the links should be removed from the 
docs (independently of the above pull), but should unused 
undocumented public templates also be removed?
