Description

Following #709, we realized there are other misuses of constructors which we should reject. Some of these will also need to be addressed in the frontend.

  • Reject constructors with variable result sorts.
  • Reject axioms with \equals between different constructors.

Research direction

Start by reading issue #709 and tracing the current constructor-validation paths in the Haskell backend, then identify the corresponding frontend validation mentioned here. Done means definitions with variable result sorts and axioms equating different constructors are rejected in the relevant backend and frontend paths.
