    /*
     * If regexp is not an object of type RegExp, it is replaced with the
     * result of the expression new RegExp(regexp).  Let string denote the
     * result of converting the this value to a string.  String is searched
     * for the first occurrence of the regular expression pattern regexp if
     * regexp.global is false, or all occurrences if regexp.global is true.
     *
     * The match is performed as in String.prototype.match, including the
     * update of regexp.lastIndex.  Let m be the number of matched
     * parenthesized subexpressions as specified in section 15.7.5.3.
     *
     * If replaceValue is a function, then for each matched substring, call
     * the function with the following m + 3 arguments. Argument 1 is the
     * substring that matched. The next m arguments are all of the matched
     * subexpressions. Argument m + 2 is the length of the left context, and
     * argument m + 3 is string.
     *
     * The result is a string value derived from the original input by
     * replacing each matched substring with the corresponding return value
     * of the function call, converted to a string if need be.
     *
     * Otherwise, let newstring denote the result of converting replaceValue
     * to a string. The result is a string value derived from the original
     * input string by replacing each matched substring with a string derived
     * from newstring by replacing characters in newstring by replacement text
     * as specified in the following table:
     *
     * $& The matched substring.
     * $‘ The portion of string that precedes the matched substring.
     * $’ The portion of string that follows the matched substring.
     * $+ The substring matched by the last parenthesized subexpressions in
     *      the regular expression.
     * $n The corresponding matched parenthesized subexpression n, where n
     * is a single digit 0-9. If there are fewer than n subexpressions, “$n
     * is left unchanged.
     *
     * Note that the replace function is intentionally generic; it does not
     * require that its this value be a string object. Therefore, it can be
     * transferred to other kinds of objects for use as a method.
