Re: Large programming project in SISC almost finished

Sorry, I've been having trouble with the older email address on the list...

Great to hear about your programming project!  Re: compilation times,
it is well known that the macro expander on which SISC is based,
psyntax, is rather slow, especially in SISC.  It is a goal to move
away from that expander to the Andre Van Tonder expander, which has
nearly exactly the same user facing API, but is much faster.

I'm also working on integrating the optimizer from Twobit, which is
the basis for Larceny and recently MzScheme, which gives us much more
advanced optimization that we currently have.  This should increase
both users' code and the performance of SISC (since much of SISC is
obviously written in Scheme).  I can't say for certain how large the
effect will be though.

Now, off to take a look at the program...
