  "message": "Inline is{Integer,Double,Symbol,List,...} with instanceof\n\nMost places that type-test a Term immediately downcast if the type\ntest is successful. The Java JIT is used to seeing \"x instanceof Foo\"\nbefore \"((Foo) x)\" and can optimize the type-test and downcast logic\nin machine code to only check the type once.\n\nTake advantage of that by swapping out the isXxx() methods on Term\nfor proper instanceof checks in the Java code.\n\nFlip the logic for $cut around to be more like human written code\nwhere the common success path is the term is the correct type and\ncan be immediately downcast. JITs expect this flow as it happens\nso often in Java source, and $cut happens often in the Prolog meta\ninterpreter.\n\nChange-Id: I4ba34cab751b6060a3b1cc1adbf75ed0019b36fd\n",
