Yes you know? You know that this is an array slice? I think you meant $_[0] there.

I meant $_[0], the yes I know was for writing stupid code.The error was because I have to hand copy the code from one pc to another because one doesn't have internet.	[reply] [d/l]

I meant `$_[0]`, the yes I know was for writing stupid code. The error was because I have to hand copy the code from one pc to another because one doesn't have internet. The biggest error being not that of using `@_[0]` instead of `$_[0]`, which is valid syntax and fundamentally does the right thing, but that of not putting the "yes I know..." part behind a comment sign, which does not.
