rxvt-unicode, my favourite terminal, now embeds a Perl interpreter to do various bits of DWIM magic that I'm yet to fully explore. From the homepage:

Embedded perl, for endless customization and improvement opportunities, such as:

• Tabbed terminal support.
• Regex-driven customisable selection that can properly select shell arguments, urls etc.
• Selection-transformation and option popup menus.
• Automatically transforming the selection once made.
• Incremental scrollback buffer search.
• Automatic URL-underlining and launching.
• Remote pastebin, digital clock, block graphics to ascii filter and whatever you like to implement for yourself.

Here's urxvt.pm and some plugins to whet the appetite.
