Oh, I see what you're talking about.  That's a closure.  It's a language
feature, so changing that behavior would be significant.  This shouldn't
be a problem if you simply avoid using closures in a recursive
algorithm.  In your example, I believe only the value of $i will be
saved each time, since $funnierstuff will go out of scope at the end of
the block and get garbage collected.
