Is there any way of picking up, at compile-time, all pointer types in
one test?
What you want is `is(T : void *)` but probably to also catch all
constancy flavors, `is(immutable(T) : immutable(void*))`
When you use `==` in an `is` expression, it's asking
Just to be clear where the argument goes (from templates parameters ext.):
``is(InputType : T*, T)``
std.traits : isPointer
or
``is(int* : T*, T)``
