The documentation says:
template isInstanceOf(alias S, T)
---------------------------
Returns true if T is an instance of the template S.
But, is isInstanceOf supposed to return true if T is a subtype
of an instance of the template S ? (but is not an instance of
the template S). Currently it does return true if T is a
struct, and doesn't if it's a class:
I'd say "works as expected". 'alias this` is not equivalent to
inheritance, it allows to type to completely act as another. And
`isInstanceOf` checks for strict matching. It will work with
classes if `alias this` is used there.
