Unpacking is nice and it's good to see this feature not only in Python...

But I'm afraid you are missing the point here.

"pattern matching" a la Haskell allows to filter for literal arguments not only types like demonstrated for multi subs.

For instance a naive Fibonacci (in pseudo-code) can look like this

Multi fib(0|1) = { 1 };

Multi fib($i)  = { fib($i-1) + fib($i-2) };

Can I do this with multi subs in Perl 6?
