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