Tim,
Did you actually read this article? In fact the article
contains the
specific reason why you should *not* be converting BOOT
code to Lisp:
(my emphasis ** ** below):
---------
...
Domain Specific Languages
In this article we've already encountered two domain
specific
languages: Ant (specific to dealing with project builds)
and our
unnamed mini-language for dealing with to-do lists. The
difference is
that Ant was written from scratch using XML, an XML
parser, and Java
while our language is embedded into Lisp and is easily
created within
a couple of minutes.
We've already discussed the benefits of DSLs, mainly why
Ant is using
XML, not Java source code. **Lisp lets us create as many
DSLs as we
need for our problem.** We can create domain specific
languages for
creating web applications, writing massively multiplayer
games, doing
fixed income trading, solving the protein folding
problem, dealing
with transactions, etc. We can layer these languages on
top of each
other and create a language for writing web-based trading
applications
by taking advantage of our web application language and
bond trading
language. Every day we'd reap the benefits of this
approach, much like
we reap the benefits of Ant.
Using DSLs to solve problems results in much more
compact,
maintainable, flexible programs. In a way we create them
in Java by
creating classes that help us solve the problem. The
difference is
that Lisp allows us to take this abstraction to the next
level: we're
not limited by Java's parser. Think of writing build
scripts in Java
itself using some supporting library. Compare it to using
Ant. Now
apply this same comparison to every single problem you've
ever worked
on and you'll begin to glimpse a small share of the
benefits offered
by Lisp.
-------
BOOT is just another DSL. Writing Axiom internals in BOOT
does not
mean that we are no longer use Lisp, rather it means we
are simply
using Lisp in the way it was intended to be used.
Regards,
Bill Page.

It is a gentle introduction to the reason why I'm
moving
all of the internal code to common lisp.
