in thread isa() on any scalar

As I mentioned, if $value is not a valid invocant, it is an exceptional case.

I'm not aware of any other idiom that respects potentially-overridden isa() methods and handles potentially invalid invocants in one statement. If you know one, please share.

Scalar::Util's blessed() is pretty good, but that technique disallows calling isa() as a class method. Sometimes that's good. Sometimes it's not.
