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.
