| michael@0 | 10 | * SUMMARY: This test arose from Bugzilla bug 57043: |
| michael@0 | 11 | * "Negative integers as object properties: strange behavior!" |
| michael@0 | 12 | * |
| michael@0 | 13 | * We check that object properties may be indexed by signed |
| michael@0 | 14 | * numeric literals, as in assignments like obj[-1] = 'Hello' |
| michael@0 | 15 | * |
| michael@0 | 16 | * NOTE: it should not matter whether we provide the literal with |
| michael@0 | 17 | * quotes around it or not; e.g. these should be equivalent: |
| michael@0 | 18 | * |
| michael@0 | 19 | * obj[-1] = 'Hello' |
| michael@0 | 20 | * obj['-1'] = 'Hello' |
