Okay. I should have checked which post you were responding to. I thought you were saying that you used split to deliberately, implicitly split to @_;

I also use shift/pop implicitly on @ARGV, especially in one liners. But in scripts I have tried to force myself to explicitly state @ARGV. I still use implicit shifts and pops within subs.

But LanX was only suggesting some features be disable if you used no oddities; or similar, so it wouldn't stop anyone doing so, unless they chose not to. Kinda of a cut down, runtime actioned perl::critic, but without the dogmas...
