in thread Action at a great distance

Did you test this?

use strict; use Test::More tests => 1; my @cb = ( sub { $_[0] = reverse $_[0] }, sub { $_[1] = reverse $_[1] }, ); my @args = qw( one two ); for my $cb (@cb) { $cb->((@args)); } is_deeply( \@args, [qw( one two )] );

Besides that, any argument passing in Perl has that drawback.
