Re: Using incremental parsing in Emacs

Or rather, my proposal was based on the "standard" way incremental
parsing works (e.g. syntax-ppss works the same way).

The question is how quickly this stops the parsing: any delay here
is very costly because the Elisp execution will have to sit idly waiting
for the parser to stop before it can continue its own execution.
