Update: made the script a bit nicer,
I haven't seen this documented anywhere, but a double colon at the end of a word is removed and makes a bareword that works even under strict, only it warns that "Bareword "%s" refers to nonexistent package".
Just adding random unneccessary junk to a simple script doesn't make it a good obfu.
Come on, you should know better than this.
