I am not porposing to take this over. Frankly, I don't care enough,
because I don't ever use "each". But I had written a reply, of which I'm
not use if I ever sent it. In this, I proposed to give each a lexical
scope, possibly optional. That way, even if you do recursion in a
function that uses each, you'd get a *different* iterator for every time
you come across it. Would that solve your problem? I think it could.
As for the "possibly optional" lexical scoping: the next syntax is a bit
ugly, but it shows some potential:
while(my($key, $value) = my each %hash) { ... }
