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