I get: Modification of a read-only value attempted at - line 2. I'm guessing that's not what was expected? That was with perl 5.8.0 on Unix, BTW.

Well, you guessed right {grin}. I'm using 5.8.3 from a Debian package, and don't have any guesses off the top of my head as to which piece is causing the error.

Sorry it didn't work for you (and the other PMer who responded whom it didn't work for). I guess relying on specific warnings for a japh probably isn't the most portable way to make it happen {grin}.
