    1.13 + * See http://bugzilla.mozilla.org/show_bug.cgi?id=72773
    1.14 + *
    1.15 + * See ECMA-262 Edition 3 13-Oct-1999, Section 8.6.2 re [[Class]] property.
    1.16 + *
    1.17 + * Same as class-001.js - but testing user-defined types here, not
    1.18 + * native types.  Therefore we expect the [[Class]] property to equal
    1.19 + * 'Object' in each case -
    1.20 + *
    1.21 + * The getJSClass() function we use is in a utility file, e.g. "shell.js"
    1.22 + */
