Adapt Y. Bertot's path on private inductives (now the keyword is "Private").
A quick and dirty approach to private inductive types
Types for which computable functions are provided, but pattern-matching is disallowed.
This kind of type can be used to simulate simple forms of higher inductive types, with
convertibility for applications of the inductive principle to 0-constructors
