(names : Array Lean.Name)
(prefixArgs : Array Lean.Expr)
(arities : Array Nat)
(termArgs : Lean.Elab.TerminationArguments)
:
The termination arguments must not depend on the varying parameters of the function, and in a mutual clique, they must be the same for all functions.
This ensures the preconditions for ArgsPacker.uncurryND.

If the termArgs map the packed argument argType to β, then this function passes to the
continuation a value of type WellFoundedRelation argType that is derived from the instance
for WellFoundedRelation β using invImage.
