Yep. I haven't looked at it since Jaguar came out. There is an F-Script 
add-on called F-Script Anywhere that lets you load an F-Script 
interpreter into any running Cocoa application. This is useful for 
exploring a third party app to see what classes it is using. Anyway, 
that's kind of OT.

It *does* work the other way but AFAIK you can't really create a new 
class in F-Script or subclass a Cocoa class. It has a mechanism called 
a block which lets you wrap up a bit of F-Script code in an object. 
This object (IIRC) responses to the value: selector. For example, you 
can create a block and set it as the target of an NSButton and set the 
action to the selector #value. This works but it is nowhere near as 
elegant or as powerful as what PyObjC can currently do. It may still be 
interesting to look at because there is a lot of common ground and, as 
Jack mentioned, it is open source.

On another note, has anyone here looked at CamelBones? I'm not really a 
Perl person but has anyone looked at how it does the Perl-ObjC bridge? 
Could be interesting.
