What does /prog/ use for CGI?

Since Ruby is slow as fuck, Python is forced indentation of code, Perl is http://www.ex-parrot.com/~pdw/Mail-RFC822-Address.html and PHP is fail on a cosmic level, what does /prog/ prefer when dealing with CGI? I seriously doubt C and Haskell.

I extend Inferno's Web server for my private stuff.  For work, I use Perl.  With some discipline (use strict, perl -w, put comments in /x REs, write PerlDoc, read "perldoc perlstyle") it is actually possible to write maintainable Perl.
