Re: Multiple-dispatch on functions

[Me]

Dan, I don't immediately see how per object/class dispatch
control helps to make multimethods pluggable. Perhaps a
multimethod (a set of methods) is a class/object? Is there
a general mop for dispatch?

More generally:

How would you handle making (multimethod) dispatch pluggable
when built in types are involved?
