If you rewrite the loop as: 
while (my ($key, $func) = each %Movement) {
    $foo->$func;
}

then you avoid the problem altogether, and you also avoid having to drop the whole key list onto the stack and dereference the hash needlessly.

I think each is underused, and is a better idiom for many loops which use keys.
