Dear Christian,

great that you pop in -- you are not at RISC-Linz anymore, are you?

This is great news! I suppose, however, that it parses only the nopile syntax,
doesn't it?

I disagree slightly :-)

Am I correct that Aldor is able to compile to lisp? Then it would probably be
possible to run this Aldor parser in a Lisp image, maybe our Lisp gurus could
do some magic with this?

In fact, I know nearly nothing about compilers and interpreters. So maybe
somebody could detail here the bits and pieces needed to morph the current Spad
compiler and interpreter of Axiom into an Aldor compiler and interpreter for

As far as I understand, one "problem" is that the Axiom interpreter knows quite
a bit about the Algebra, to do it's type inference, which is a "must have"...
