Folks,I've just opened up an svn on
http://code.google.com/p/objective-c-caml-bridge/.
This is an alpha-level release of a bridge between OCaml and Objective C (or
more precisely, Cocoa APIs) for MacOSX.
It's been barely tested, only w/ ocamlc 3.09.3 and Tiger 10.4.11 and still
lacks many features (e.g. invoking OCaml methods from ObjC).
However, it gets an "Hello World" command-line program compiled and running,
all from automatically generated stubs.
Don't expect to understand much of the bridge's technical aspects unless
you're expert-level in OCaml (objects, labels, C-interface)
and intermediate in ObjectiveC (NSInvocation, Foundation, AppKit).

At this point I'm looking for feedback on naming conventions, overall
expectations on verbosity and utilization.
Start w/ reading the Wiki if you're interested, and shoot me an email.
License is (new) BSD style.
Thanks for your interest,
