Am I naive in thinking you can write clever code so long as your commenting for it increases exponentially with respect to "unit" increases in cleverness? It seems to be the main reason Perl and other languages with delimiters let you write one line of code on any number of lines you choose. It's the reason for the /x flag on regular expressions, which certainly hold a fair amount of potential abuse of cleverness.

Also, "cleverness" should really be disambiguated from "obfuscation," which is a deliberate attempt to conceal the intent of code. As a simple example, $|++ isn't clever.
