Proof step 26 from proof coerce-okval (conclusion)

⊦ okval(coerce(val, ty), ty) ↔ ty ≠ abstract_type

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ coerce(val, abstract_type) = noval
Proof step 2:
⊦ ¬ okval(val, abstract_type)
Proof step 25:
⊦ ty = abstract_type, okval(coerce(val, ty), ty)

Rule argument

[emptyarg]
