However is this answer safe? If %foo (which appears to be global) already had something in it, you have completely messed that up. Plus you changed the scope horribly with your my you couldn't resist.

The reverse answers may hide intent, but they are less likely to break other hidden behaviour assumptions which something, somewhere, might rely on.

So while I like your answer better, I would suggest that you note the assumptions you made...
