in thread Strictly nested sub warnings

Out of curiousity, why #5? I don't question that it's the case (you know better than me by job lots), I just wondered what the reason was.

for(split(" ","tsuJ rehtonA lreP rekcaH")){print reverse . " "}print "\b.\n";

    Especially if you're joining lots of vars with short strings, concatenation can leave you drowning in symbols.
      For short variables I agree 100%.

      For more complex variables, I tend to go back to concatenation to make sure I get what I want.

      print "Guess what you get: $hashref->{$lookup1[$i]}->{$lookup2[$i]}\n" +;

      Also, with syntax highlighting, punctuation actually makes the code more readable than interpolation IMO.

    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
