There is no automatic wrapper, you'll have to bind each method by-hand.
Also, you need to store the actual instance into a field of the neko object.

const char *r;

DEFINE_PRIM(new_myclass,0);
DEFINE_PRIM(mymethod,1);
----------------------------------------
// from neko code :
new_myclass = $loader.loadprim("[EMAIL PROTECTED]",0);
myclass_proto = {
mymethod => $loader.loadprim("[EMAIL PROTECTED]",1);
};
// constructor
myclass = function() {
var o = $new(null);
$objsetproto(o,myclass_proto);
o.__inst = new_myclass();
return o;
}
// test
var c = myclass();
c.mymethod(0);
