    1.10 + * Date: 26 November 2000
    1.11 + *
    1.12 + *
    1.13 + *SUMMARY: Passing a RegExp object to a RegExp() constructor.
    1.14 + *This test arose from Bugzilla bug 61266. The ECMA3 section is:      
    1.15 + *
    1.16 + *  15.10.4.1 new RegExp(pattern, flags)
    1.17 + *
    1.18 + *  If pattern is an object R whose [[Class]] property is "RegExp" and
    1.19 + *  flags is undefined, then let P be the pattern used to construct R
    1.20 + *  and let F be the flags used to construct R. If pattern is an object R
    1.21 + *  whose [[Class]] property is "RegExp" and flags is not undefined,
    1.22 + *  then throw a TypeError exception. Otherwise, let P be the empty string 
    1.23 + *  if pattern is undefined and ToString(pattern) otherwise, and let F be
    1.24 + *  the empty string if flags is undefined and ToString(flags) otherwise.
    1.25 + *
    1.26 + *
    1.27 + *The current test will check the first scenario outlined above:
    1.28 + *
    1.29 + *   "pattern" is itself a RegExp object R
    1.30 + *   "flags"  is undefined
    1.31 + *
    1.32 + * We check that a new RegExp object obj2 defined from these parameters
    1.33 + * is morally the same as the original RegExp object obj1. Of course, they
    1.34 + * can't be equal as objects - so we check their enumerable properties...
    1.35 + *
    1.36 + * In this test, the initial RegExp object obj1 will not include a
    1.37 + * flag. The flags parameter for obj2 will be undefined in the sense
    1.38 + * of not being provided.
