Similarly, if the ISA chain of any class changes at runtime, do all of the multi caches get wiped? Or do you look at the isa tree before changing it to just clear part of the cache?

    Caveat: I have not looked at the code at all yet...

    • I haven't handled the case where you add new multis at runtime yet), but yes, it'll just clear the cache for that bunch of multis. It's easy enough to do (few lines of code); it's on my task list and will be done before we merge the branch in. We don't support changing the isa chain of a class at runtime yet in Rakudo, but I expect once we do then it will just wipe all MMD caches.

      We may be able to do something smarter in the future. But for Rakudo 1.0, I'm not really interested in making doing things like c
