Unparse should be flexible to unknown implementations

Description

Problem

Unparsing a type, often during unit testing via prn, requires the
type system implementation to be specified. This is too restrictive.

Solution

The unknown implementation should verbosely print types, and ignore
the current namespace.

Notes

Implementation extracted from this branch.
