Real is a role, not a type. Both Num and Rat happen to do Real, so the
type checking is ok. This would work OK with a type too -- you can
safely store a Num in a `my Cool $foo` as well.
You can't do anything to make the ^name method return Real. There are a
few ways to check this, though. The most idiomatic is smartmatch:
> my Real $f = 3;
3
> $f ~~ Real
True
That checked that the value of the variable does Real. If you want to
check the type of the container:
> $f.VAR.of
(Real)
That explains it. Thank you!
