In this case, "is(immutable(int) : int)" is true, but this is not true of all
types, so array won't be able to do this for any and all types.

That said, it doesn't seem ridiculous to me either:
1) Create an array of whatever an IFTI on the element type would produce.
2) Simply make mutable elements for types that can safely be converted to their
Unqual type.

However, this would be a change of behavior, which may or may not be an
improvement, and may or may not break code.
