The idea was that any concrete type that implements that interface must satisfy its axioms. Even if the compiler ignored these axioms, one can write a support program that can generate a set of comprehensive tests based on these axioms.

Sounds like Eiffel, whose compiler had support for checking pre and post conditions (and maybe invariants?) at runtime, or disabling the checks for “performance” mode.
