Well, this is quite obvious, and falls more into the "Wow, that's an interesting feature" realm than the "line noise with added punctuation" area.

I am, in fact, a little worried that I can do it this way (using main) at all.

$m = tie $m, main; print " hacker\n$m"; sub STORE {print 'another '} sub TIESCALAR {print 'Just '; bless [], $_[0]} sub FETCH {print 'perl';''}
