I don't like that either, just because it's Perl :-)

I'm not fluent in Perl, and didn't know $^I. Actually, that's better,
yes. (And my script is already rewritten.)
One thing I don't like about both scripts is, that the timestamp of
a file changes with that, even if there are no changes. Anyone knows
another predefined variable/trick that doesn't hurt performance (and
readability) too much?
