Come on now, really. `print "$_ is $ENV{$_}\n" for sort keys %ENV;` 1 character less, plus it beats the snot out of using map where it is not needed.

Why not needed? map isn't called in void context; on the other hand the `for` variant calls print repeatedly, while the other invokes it only once. </nitpick> Makeshifts last the longest.	[reply]
