- -- A critical invariant in this approach is that if an id in the generic

- -- will resolve to the homologous entity in the instance, even though
- -- the enclosing context for resolution is different, as long as the
- -- global references have been captured as described here.
-
- -- Because instantiations can be nested, the environment of the instance,
- -- involving the actuals and other data-structures, must be saved and
- -- restored in stack-like fashion. Front-end inlining also uses these
- -- structures for the management of private/full views.
