in thread Strictly nested sub warnings

It's fairly minor, but using concatenation when you could use interpolation instead tends to obscure the result you are aiming for. Compare the following two print statements:

use strict; use warnings; my $tsuJ = 'tsuJ'; my $rehtonA = 'rehtonA'; my $lreP = 'lreP'; my $rekcaH = "\nrekcaH"; print join ' ', map {scalar reverse} split / /, $tsuJ . ' ' . $rehtonA + . ' ' . $lreP . ' ' . $rekcaH; print join ' ', map {scalar reverse} split / /, "$tsuJ $rehtonA $lreP +$rekcaH";
True laziness is hard work
