Hi,

Found it!

static VALUE
main_to_s(VALUE obj)
{
    return rb_str_new2("main");
}

I jest, of course. :) We also see it actually declared/defined this way:

void
Init_top_self()
{
    rb_vm_t *vm = GET_VM();

    vm->top_self = rb_obj_alloc(rb_cObject);
    rb_define_singleton_method(rb_vm_top_self(), "to_s", main_to_s, 0);
}

I guess, it needs to be called something - or *should* be called something,
just to distinguish it! So here's a way.

Cheers,
Arlen
