  * 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'
