    Description

      It looks like unknownAsFalse duplicates IS_TRUE handling.

      In other words, withUnknownAsFalse(true). simplfy(expr) is more or less comparable to simplify(isTrue(expr))

      Implementing IS_TRUE/IS_FALSE/... simplification possibilities might make unknownAsFalse obsolete.
