It's going to be a really, really, *really* hard sell to get us to
export any sort of external API to the parser internals. At least
if by "API" you mean something other than "we will whack this around
to an indefinite degree on no notice, and don't even think about
What exactly is the goal that you think such a thing would serve,
anyway? The fragments on the referenced web page don't leave me with
any warm feelings about how well the idea has been thought through.
