Re: Re: Re: Re: $_ haters anonymou

Well why not have $_ be automatically lexical?

Works perfectly well. But breaks backwards compatibility. But I think it will happen in Perl 6.

Enh, but then it's impossible to define subroutines that work like built-ins such as chomp. I do that not infrequently. However, I wouldn't mind having to go through hoops to get there. Perhaps a subroutine attribute would have to be set to allow you access to `$_`. `sub mychomp : getunderscore { s[${/}\z][]; }` [download] That way, no one could clobber `$_` without intending to. And we could also add a pragma to disallow code outside of your file (or perhaps package) from clobbering `$_` even if it wanted to. -dlc	[reply] [d/l] [select]
