i've switched over all my 'concrete' classes quite easily, looks like i'll
have to do some placement new (finally an excuse to use it) tricks for my
more complex classes

but its all working fine now, cheers :)

Yes.. My alloc/free looks something like this (ruby-1.8.0)


void Free(Klass *p) {
	delete p;
}

VALUE Alloc(VALUE self) {
	Klass* p = new Klass();
	return Data_Wrap_Struct(self, 0, Free, p);
}

void KlassInit() {
	VALUE h = rb_define_class("Klass", rb_cObject);
	rb_define_alloc_func(h, Alloc);
}
