or, rather 
for my $str (@strs) {
    my $len = ( () = $str =~ m{ 0+ | 1+ }xg ) + (
          $str =~ m{ 000 | 111 | (.)\1 .* (.)\2 }x ? 2
        : $str =~ m{ (?: ^ (.)\1 | (.)\2 $) }x     ? 1
        : 0
    );

    print $len, "\n";

...anyway, I'm now too bored to think whether that's the correct solution and I'll leave the rest of that little programming exercise to you.

Your problem is that you're trying to write overly compact code even though you don't know Perl very well. And, naturally, writing the retarded equivalent of JAPHs is not a good way to learn Perl - or any programming language, for that matter. Just saying.

I recommended you to learn Forth a while ago, and I still do. BUK suggested Python, but its significantly more verbose than Perl and you won't like it.
