Some predicate templates in std.traits does not consider alias this type.

isIntegral
isFloatingPoint
isNumeric = isIntegral!T || isFloatingPoint!T
isUnsigned
isSigned
isSomeChar
isAssociativeArray
isDelegate
isSomeFunction  when T is delegate

But others consider it.

isSomeString
isNarrowString
isStaticArray
isDynamicArray
isArray = isStaticArray!T || isDynamicArray!T
isPointer
isIterable
isFunctionPointer
isSomeFunction  when T is function pointer

I think all of them should consider alias this, because alias this type is just
a proper super-type.
