Description

be generalised outside the PL scope, once we have typeclasses to express that a type possesses an

Research direction

Start at Cslib/Logics/Propositional/Defs.lean lines 132-134, where the current declaration is scoped to PL. Review the surrounding propositional definitions and the planned typeclass support; done means the declaration is generalized beyond PL using a typeclass for an implication connective.
