Hello Krystian,

Thanks for the introduction and for some details of your GSoC
proposal. I would be very pleased if you receive approval to proceed
with the work you describe.  However I would like to make some
observations and to ask a few questions. Although it might sound
otherwise, I do not intend this in any way as a criticism.

I understand of course that your proposal is motivated by your PhD
research. It seems to me however that the other fork of Axiom - the
OpenAxiom project has for sometime had as one of its primary goals
improvements to the SPAD compiler and the SPAD language itself.  Gaby
has even mentioned a goal of replacing Lisp as the underlying runtime
system that sounds very similar to your work.  The FriCAS project on
the other hand has (mostly) focused on improvements to the SPAD
library and the addition of new mathematical algorithms. Now FriCAS is
also the only fork of Axiom that already supports Aldor as an
alternative compiler for the FriCAS library. So my first question is:
How does your proposal differ from what has been proposed and done so
far in OpenAxiom and what is already available in Aldor?

My second question also applies to OpenAxiom and I do not think it has
been fully addressed there:  What is the underlying motivation for
replacing Lisp with some other run time environment?  It might be
interesting to observe that in addition to the Lisp target, Aldor also
has it's own native standalone run time environment.  If your work is
incorporated into FriCAS how would that impact the possible use of
Aldor?

Finally, are you thinking of any improvements to the SPAD language itself?

Regards,
Bill Page.
