paragraph ‹Summary›
text ‹A generalisation of unification hints, originally introduced in \<^cite>‹"unif-hints"›.
We support a generalisation that
▸ allows additional universal variables in premises
▸ allows non-atomic left-hand sides for premises
▸ allows arbitrary functions to perform the matching/unification of a hint with a disagreement pair.

General shape of a hint:
‹⋀y1...yn. (⋀x1...xn1. lhs1 ≡ rhs1) ⟹ ... ⟹ (⋀x1...xnk. lhsk ≡ rhsk) ⟹ lhs ≡ rhs›
