the type parameter of J must match the type of its two endpoints
Example
Hint::JType::type-mismatch means the JType position supplies a term whose type does not match the expected type. The example shows the failing form first, then one way to give the checker the missing structure.
# Bad: J's type argument does not match the endpoints.
J bool motive refl zero zero p
# Better: use the endpoints' shared type.
J nat motive refl zero zero p
