* String.match( regexp )
*
* If regexp is not an object of type RegExp, it is replaced with result
* of the expression new RegExp(regexp). Let string denote the result of
* converting the this value to a string. If regexp.global is false,
* return the result obtained by invoking RegExp.prototype.exec (see
* section 15.7.5.3) on regexp with string as parameter.
*
* Otherwise, set the regexp.lastIndex property to 0 and invoke
* RegExp.prototype.exec repeatedly until there is no match. If there is a
* match with an empty string (in other words, if the value of
* regexp.lastIndex is left unchanged) increment regexp.lastIndex by 1.
* The value returned is an array with the properties 0 through n-1
* corresponding to the first element of the result of each matching
* invocation of RegExp.prototype.exec.
*
* Note that the match 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.
