Well yeah, but aren't you just back to square one?

C:\test>perl -nwle"print $n = +(split)" Use of implicit split to @_ is deprecated at -e line 1. Name "main::n" used only once: possible typo at -e line 1. foo 1 foo bar 2

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?

    D'Oh! I forgot to -w when I tested it. It's incredible how annoying this little thing can be!!! All in all I would regard the assignment to @_ and the connected warning as spurious, since split is not called in void context. But... they're there!
