I'm not sure the indirection in `scm_init_stacks ()' is needed since it
uses STACK_LAYOUT for both VTABLE and SCM_STACK_TYPE, and `make-struct'
doesn't look at the vtable's vtable anyway (when creating instances of
SCM_STACK_TYPE).

More generally, a three-level architecture like the one you suggest
would look fishy. For instance, GOOPS and other CLOS derivatives have
<object> and <class>, representing respectively the "base" and "meta"
levels, but they have no need for <class-class>, <class-class-class> or
some such.
Thanks,
Ludovic.
