      8 * Date: 26 November 2000
      9 *
     10 *SUMMARY: Testing numeric literals that begin with 0.
     11 *This test arose from Bugzilla bug 49233.
     12 *The best explanation is from jsscan.c:               
     13 *
     14 *     "We permit 08 and 09 as decimal numbers, which makes
     15 *     our behaviour a superset of the ECMA numeric grammar. 
     16 *     We might not always be so permissive, so we warn about it."
     17 *
     18 *Thus an expression 010 will evaluate, as always, as an octal (to 8).
     19 *However, 018 will evaluate as a decimal, to 18. Even though the
     20 *user began the expression as an octal, he later used a non-octal
     21 *digit. We forgive this and assume he intended a decimal. If the
     22 *JavaScript "strict" option is set though, we will give a warning.
