I don't know, but I am more impressed with obfuscations which actually run on a variety of valid installations. I'm not trying to be snide, but I think there's a fine line between the use of obscure language constructs, and the (ab)use of accidental implementation issues.

I couldn't run this on Windows (ActiveState 5.6.0), nor on Solaris (5.005_03). Since there's no indication of what version of perl this expects, I'll try it on a Linux 5.8.0 when I get home. Maybe someone else can post a spoiler?
