* interp/compiler.boot (evaluateConstructorModemap): Rename from
substituteInfoFunctorModemap. (constructorCondition): New. * interp/define.boot (compDefineCategory2): Compute dual signature early on. (compDefineFunctor1): Likewise. (typingKind): New. (deduceImplicitParameters): Use it. * interp/database.boot (modemapsFromCategory): Take a first argument as a DB. Tidy. Adjust caller. Add constructor condition. (modemapsFromFunctor): Likewise. Lose last argument. (mkDatabasePred): Remove. (formal2Pattern): Likewise.
