This test checks for a couple of specific ways that bugs in toString() round trips have changed the meanings of functions with var declarations inside for loops. On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE". PASS unevalf(eval(unevalf(f1))) is unevalf(f1) PASS unevalf(eval(unevalf(f2))) is unevalf(f2) PASS unevalf(eval(unevalf(f3))) is unevalf(f3) PASS unevalf(eval(unevalf(f4))) is unevalf(f4) PASS unevalf(f2) != unevalf(f3) is true PASS successfullyParsed is true TEST COMPLETE
