Please don't use "inherits" when talking about these core types. Classical
inheritance just doesn't work with the varied sets of numbers. All those
stories you were

What is (or should be) going on here here?
My personal favorite is
[5] none of the above -- that should be a type error. ;)
But only if MMD doesn't find a unique handler. That is I would
favor 'type error' =:= 'no handler || ambiguo

If that's the case, then if I change a variable that isa Str (that isa

I still don't quite have a handle on the object system. Maybe:
subtype Num of Str where /^ $/;
?
Maybe s/
