Absolutely! Every concept in Metal is defined solely by its type, no
assumptions whatsoever are made about the presence of nested types or
values . As far as Metal is concerned, types need only be declared and
may even be left undefined.

My intention is to expand the `external` module to provide adaptors to
other libraries, Hana included, just like it provides for MPL now.
