FSClass for Mac

FSClass is a "meta-class" that allows programmers to create new classes directly in F-Script, instead of having to write them in Objective-C. No additional syntax or keywords are necessary, so the core F-Script language is unaffected and classes can be created programmatically. Methods are implemented with F-Script blocks, and instance data is stored as Key-Value Coding-compliant properties. Objects created with FSClass are almost as fast as native Cocoa objects, and can be used by compiled Objective-C code.
