Proposal for exact matching and matching at a position in RegExp

I had mentioned to Brendan at the last TC39 that you had ported narcissus and had observed the cost of match.
There is a new global regexp parameter called 'y' which prevents the copy from occurring.
I've taken a look at narcissus and made some edits adding y to match. Both Brendan and Bob Clary
have advised on how to get the changes into mercurial on mozilla if you are not a developer within mozilla.
I can forward you these emails and we could review respective changes if you would like and its ok with
mozilla. The mozilla bug id is https://bugzilla.mozilla.org/show_bug.cgi?id=542621

Does anyone have any comments on this?
Can I put it in a place where it will be considered for the next
ECMAScript? The overall idea seems relatively uncontroversial since
it was already implemented by Mozilla (for the exact same reason). I
have proposed a specific API enhancement too.
