Research direction
Start with Cslib/Logics/Propositional/Defs.lean at lines 123-125 and inspect the surrounding PL-specific definition. Determine how the proposed typeclass for an implication connective is intended to support generalization beyond PL. Done means the definition is no longer limited to PL while preserving the existing behavior.
