Oh, Thanks. This is very good document.
I saw http://wiki.ecmascript.org/doku.php?id=harmony:regexp_match_web_reality
and http://wiki.ecmascript.org/doku.php?id=strawman:match_web_reality_spec .
And I've fixed for my RegExp runtime to accept examples in it.

BTW, I thought that the example in
http://wiki.ecmascript.org/doku.php?id=strawman:match_web_reality_spec
  exec(/(?=a)+/, "");
should return false. Is it right?
