I definately like the idea of having something like that. It probably wouldn't be used much, but it is nice to have the option. One thing though, can't you accomplish the same thing by slurping everything, then poping the block off of the array?

Then we could do: sub for ([EMAIL PROTECTED], &block) {...} Proposed behavior of *?@ : All Arguement to Parameter mapping left of it are processed Left to Right. Once seen, the mapping starts over right to left. Everything remaining is slurpable. Yes, it's more expensive to use, just like the RE version, but shouldn't impact performance _too_ bad when it's not, since the behavior will be detectable at compile time. Thoughts?
