When I made the suggestion to give the perl parser enough API to let
an editor use it for syntax highlighting, I was thinking of an editor
written in C with embedded perl. Such as emacs or vi.

I didn't say that anyone should actually do it :-)
[or that it wouldn't be usably fast on anything expensive enough to come
with less than 1Gb RAM as standard]
Just that it would be nice if the parser API were flexible enough to make
it possible (if not easy) for someone to do it.
As it seemed to be a bit of parser API we'd not yet considered.
And this is the parser-api list, so it seemed very on topic.

I think I'm not wrong in saying that making the parser state totally
encapsulated makes the parser restartable and goes a long way to making
it re-entrant.
