Wanted (source)code plugin for Wordpress

The past days I’ve been posting stories with a few code samples – Perl, PHP, Javasscript and/or HTML. While Wordpress is fantastic to a number of things, handling sourcecode examples in the posts, reallly isn’t one of them.

I’ve been playing with a number of plugins, but none of them really works for me. What I’m looking for is this:

• It must be able to handle HTML, Javasscript, PHP and Perl sourcecode.
• The code samples should work with the visual editor (preferably entered in this, but ”code mode” is quite alright) – Visual post editing shouldn’t break the code example.
• The plugin should be alive (maintained and tested with recent wordpress releases).

I would have thought it would have been easy to find a plugin that covered the above requirements, but so far I’ve had very little luck – any suggestions?
