Part of this will be some kind of synchronisation primitive. I don't
much care what it is, but somewhere I need a way to make a process wait
until something happens rather than just a constant time.
Paul, what you have described sounds like a reactive system. Have you
looked into AFRP/Yampa?

Fellow Haskellers and C-- enthusiasts,
I am pleased to announce the initial alpha release of a C-- frontend
(parser, pretty printer, and semantic checker) written in Haskell.
My goal when beginning this project was to create a modular frontend
that could be used both by people writing and
I don't have an answer. But I do have questions which may help.

Hi, I'm going slowly nuts here. Maybe someone can help me out.
I want to do some fairly straightforward discrete event simulation.
Tasks do side effects, probably in the ST monad. Every so often the
current task calls "delay n" where n is a number of seconds. This puts
the task back on a li

You have some way to go. It may be helpful to take a look at our
course on compiler construction, in which we explain how to use the
various tools we have built to build compilers and interpreters.
I suggest you download the code and the tools and the lecture notes,
and start to try to make
