I'm not sure how many people use Pike - there isn't much of a community on the web - but I downloaded it today. It is VERY similar to C lexically, so I picked up the core language in a couple of hours. However, the tutorial (the only tutorial) on the web is only for describing the core language elements, but Pike comes bundled with the GTK GUI Toolkit - but no info on how to program it. Bummer.
If anyone knows (in fair detail) and Pike/GTK, or knows where I might find a good tutorial, I would be extremely grateful ;)
Pike is pretty useless, IMO.
