| michael@0 | 8 | ** Description: Testing lazy initialization |
| michael@0 | 9 | ** |
| michael@0 | 10 | ** Since you only get to initialize once, you have to rerun the test |
| michael@0 | 11 | ** for each test case. The test cases are numbered. If you want to |
| michael@0 | 12 | ** add more tests, take the next number and add it to the switch |
| michael@0 | 13 | ** statement. |
| michael@0 | 14 | ** |
| michael@0 | 15 | ** This test is problematic on systems that don't support the notion |
| michael@0 | 16 | ** of console output. The workarounds to emulate that feature include |
| michael@0 | 17 | ** initializations themselves, which defeats the purpose here. |
