Isn't it more awkward to e.g. loop in a one-line statement over the
contents of a container?

Anyhow, here is what I think you were *really* trying to do in the
first place:

FUNCTION MyProg::INIT, a
self.c = ptr_new(a)
RETURN, 1
END

PRO MyProg__Define
class = {MYPROG, c:Obj_New()}
END

And *self.c would be the array "a" of object pointers.
