The thing is, this isn't a new match level. Rather than the enum
implicitly casting to its literal (I'm hoping I'm using the
correct word here) I'm proposing it implicitly cast to its typed
literal (Instead of A.a implicitly converting to 0, it converts
to int(0)). This would mean it would match the int since its a
direct match.
