     11  * Since regular expressions have been part of JavaScript since 1.2, there
     12  * are already tests for regular expressions in the js1_2/regexp folder.
     13  *
     14  * These new tests try to supplement the existing tests, and verify that
     15  * our implementation of RegExp conforms to the ECMA specification, but
     16  * does not try to be as exhaustive as in previous tests.
     17  *
     18  * The [,limit] argument to String.split is new, and not covered in any
     19  * existing tests.
     20  *
     21  * String.split cases are covered in ecma/String/15.5.4.8-*.js.
     22  * String.split where separator is a RegExp are in
     23  * js1_2/regexp/string_split.js
