| // // This test illustrates an opportunity to remove redundant code by |
| // // propagating inforamtion after inlining. |
| // // |
| // // The code below inlines `foo` twice, but we don't propagate that we already |
| // // know from the first `foo` that `a` is an int, so the second check can be |
| // // removed entirely. |
| // |
| // import 'package:expect/expect.dart'; |

| // main() { |
| // var a = nextNumber(); |
| // action(foo(a)); |
| // action(foo(a)); |

| // foo(x) { |
| // if (x is! int) throw "error 1"; |
| // return x + 5 % 100; |
