Thanks ikegami, I just needed to check the variables. This fixed it:

use strict; use warnings; use List::Util 'shuffle'; while (<DATA>) { my @newline = split(/\b/); for my $word (@newline) { my $first = ""; my $rem = ""; my $middle = ""; my $last = ""; ($first, $rem) = split /(?<=\b\w)/, $word if $word; ($middle, $last) = split /(?=(\w'\w+|\w)$)/, $rem if $rem; ((length $middle) == 2) ? $middle = reverse $middle : ($middle = join "", shuffle(split //, $middle)) if $middle; print "$first" if $first; print "$middle" if $middle; print "$last" if $last; } }
