in reply to Missing $ on loop variable?
Since foreach can optionally take a variable on the outside, perl interprets keys as the name of that variable, with the parans around %hash indicating the array you want to iterate over. In other words, it was expecting this:
foreach $keys (%hash) { . . . }
But since it didn't see the sigal, it threw an error about that.

I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident.
