I can do this:
struct Foo(T) { }
template bar(T : Foo!int) { }
I can check if T is a specific instantiation of Foo. But I want to
check whether T is *any* instantiation of Foo. Is this possible to do?
Otherwise I'm currently having to hardcode via:
template bar(T) if (isOneOf!(T, Foo!int, Foo!double)) { }
But having to list all possible instantiations doesn't really scale too
well.
static if can do this:
template IsAFoo(T) {
static if (is(T t == Foo!U, U)) {
enum IsAFoo = true;
} else {
enum IsAFoo = false;
}
}
