Cool++ Corion already pointed out `s/tr/y/`, but the use of `/cs` is a real win. Is there any fat left in that? Can anyone beat 29? Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". In the absence of evidence, opinion is indistinguishable from prejudice. "Too many [] have been sedated by an oppressive environment of political correctness and risk aversion."

Applying my same tricks, you can replace the `@_=();say@_` initialization by `@_=!say@_`, which is two chars shorter,yielding 31 on Windows and 33 on Unix: `-nE@_[ord]=$_,for/./g;@_=!say@_` [download]	[reply] [d/l] [select]
