Sigh. Yes, the foreach block constitues its own scope. I'm trying to write code that simulates what Perl does for you. Let me repeat what I said earlier. There's nothing declared in the block. Something is declared for the block. And the way to do that manually is by adding an outer block and do something before you enter the other block. Otherwise you'd do the thing on each iteration of the block, and that's not what you want.

You have to let go of the idea that perl puts a local() in your block.
