9 * SUMMARY: Testing left-associativity of the + operator
10 *
11 * See ECMA-262 Ed.3, Section 11.6.1, "The Addition operator"
12 * See http://bugzilla.mozilla.org/show_bug.cgi?id=196290
13 *
14 * The upshot: |a + b + c| should always equal |(a + b) + c|

88 * any argument that is of string type. For example, suppose the
89 * arguments were 11, 'a', 22. Then the eval string should be
