(multi)subroutine names

Say I have:

 multi sub foo(Array $a,Int $b) {...}
 multi sub foo(Hash %a, Int $b) {...}

and I want to (distinctly) wrap each multisub, say for testing, or AOP,
or whatever. How do I get the two different code references? As far as i
can gather from the Apocalipses and Synopses, there should be a way to
express the "long name", and use that to get the ref. Is there any
proposed syntax for this? (I ask about syntax because the semantic seems
pretty clear...)
