in thread foreach-loop-local var in sub

> I'm looking forward to my subs!

no need to wait it's just another syntax for my $sub =sub {}, just w/o the need to do dereferencing and occupying a scalar variable.

from Re: foreach-loop-local var in sub:

use strict; use warnings; foreach (0, 1) { my $i = $_; my $print = sub { print $i; }; $print->(); # 0,1 }

Cheers Rolf

    Which is what I use all the time now ;) But it feels kinda hacky, even though it works and even though it's actually documented behaviour. Getting "real" lexically scoped subroutines would feel less work-aroundish.
