I have tried CamelBones a bit, it is nice.
However, it looks likes quite a bunch of methods implementations are missing. After installing the 0.2 release I checked out the CVS, but It still lacks loads of code.
Specifically, I tried to use CBPerlScalar in an Objective-C program (wanted to use some Perl-Compatible Regular Expression) ; it didn't work as expected. Of course, it can't since :

// Get/set this variable with NSStrings
- (NSString *) getString {
    // TODO
    return nil;
- (void) setToString: (NSString *)newValue {
    // TODO

So come the question ; is there a more complete (or less incomplete) implementation sitting somewhere ?
Should I fill some of the holes myself (seems doable) and start sending patches ?
