Yes, we reply to non-fully-formed questions, too!

multi foo(Any $x) { say "general" };
multi foo(Int $x) { say "specific"; nextwith("") };
foo(42);

The above code will print specific and then general. Works in Rakudo today.

"Module inheritance" is a bit of an oxymoron, since inheritance is a relation between classes, and becomes expressed through the dispatching of methods. A module of subs is twice removed from such action. I tried the above in Rakudo. It doesn't work, but to my surprise the 'module B is A' declaration didn't throw a Big Fat Error. I think it should (to catch misunderstandings like this early), so I submitted a rakudobug about it.

Im wondering if there is (or if there should be) a way of using nextsame in a functional way (other than with multisubs) with module inheritance. Say, if you have two modules:

module A {
sub foo {say “A::foo”}
}

module B is A {
sub foo {say “B::foo”; nextsame}
}

Or is module inheritance like this not possible?
