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.
