Hey John,<br>The language you are working on - is it a EDSL in Haskell? If not, had you considered such an option?<br><br><div class="gmail_quote">On Thu, Aug 5, 2010 at 8:11 PM, Job Vranish <span dir="ltr"><<a href="mailto:job.vranish@gmail.com">job.vranish@gmail.com</a>></span> wrote:<br>

<br>John Van Enk and I are actually working on a language that's similar to C (and compiles to C), but has polymorphism, type inference and other goodies. The goal is to make working on embedded systems a bit less painful, while still being able to do anything that C can do (like run on an 8 bit micro).<br>
Hopfully, if things go as planned, we'll have a working beta out by the end of the month :)<br><font color="#888888"><br>- Job</font><div><div></div><div class="h5"><br><br><div class="gmail_quote">On Wed, Aug 4, 2010 at 5:58 PM, Don Stewart <span dir="ltr"><<a href="mailto:dons@galois.com" target="_blank">dons@galois.com</a>></span> wrote:<br>

</div>Or look at EDSLs, like Atom:<br>
