I recently started playing with Applescript Studio and am pretty impressed. I am a web developer (Java and PHP mostly) and was happy to see a way to develop light mac apps without going into C/Obj-C.
I'd really love to see apple add more official support to other languages. I think an object oriented scripting language like Python or Ruby would be a great fit and fill the niche between Applescript and Obj-C. I did see CamelBones (
http://camelbones.sourceforge.net/) which lets you develop GUI apps with Perl. Has anyone here used this or know of similar projects?
