OK. I understood that Manu says. And my yesterday comment was completely wrong.
Sorry for my misunderstanding.

Certainly, isFunction is an important template which lacks in std.traits.
Existing other function traits, isSomeFunction, isCallble, FunctionTypeOf,
return true even if given function pointer or delegate. I can agree with the
behavior is sometimes obstacle.

And more, mixing symbol and type is *a design* of std.traits. I had
misunderstood at the point. isSomeFunction is an example.

  /**
  Detect whether >>symbol or type<< $(D T) is a function, a function pointer
  or a delegate.
   */
  template isSomeFunction(T...) { ... }

I challenged implementing proposed template isVariable. Is this what you want?
