Jason Felice: gambit-objc v0.1.0 for Gambit Scheme released

I've just released gambit-objc 0.1.0.  This is the "it has the basics, and the implementation is complete enough for real projects" release.

* It gives you access to Objective-C class objects.  The easiest way is:

  (import-classes (NSString NSDictionary))

  after which, you can refer to them.

* It dynamically dispatches Objective-C methods:

  (: NSString stringWithUTF8String: "hello, world")

* It supports marshaling of native Scheme objects to C/Objective-C types for parameter and return values, including structures, selectors, all integral types, and UTF8 strings.  It wraps Objective-C objects with foreign.

* It has a objc-repl, an extended version of gsi which supports square-brace syntax, like so:

  [NSString stringWithUTF8String: "Hello, world!"]

You'll find a minimal sample Cocoa app in the distribution as well.

There are many cool things that can be added.  I'd love to collaborate, help people use it, and otherwise enable its adoption.

I'm really happy with how elegant it ended up (after a couple partial implementations were scrapped).  My next focus will be making it easy to boot on iOS and bring into iOS projects.
