| /// Please note that this test should not be executed with analyzer. |
| /// The exception is that some constant expressions are evaluated at compile time |
| /// (we don't actually promise that they are evaluated before run time, but we |
| /// know that some compile-time evaluation does take place); some of those |
| /// constant expressions have different semantics in an execution with sound and |
| /// unsound null checking. Hence we may be able to observe a different behavior. |
| /// The analyzer assumes sound null checking during constant evaluation. So, the |
| /// test should be skipped by analyzer. |
