Modifying the program is not inherently harmful, and in my opinion, modifying code that does not run under strict is usually a good idea. Not that all programs should be made to run under strict, but the fact is that it prevents a lot of subtle bugs that might not come up in normal debugging at all.

As to the problem in the original question, I'd like to ask 'why' too; why make the iteration variable global? Call-by-value is really not that expensive, and if you feel it is, use $_[0].
