| 23 | * SUMMARY: This test arose from Bugzilla bug 57043: | |
| 24 | * "Negative integers as object properties: strange behavior!" | |
| 25 | * | |
| 26 | * We check that object properties may be indexed by signed | |
| 27 | * numeric literals, as in assignments like obj[-1] = 'Hello' | |
| 28 | * | |
| 29 | * NOTE: it should not matter whether we provide the literal with | |
| 30 | * quotes around it or not; e.g. these should be equivalent: | |
| 31 | * | |
| 32 | * obj[-1] = 'Hello' | |
| 33 | * obj['-1'] = 'Hello' | |
