Me too, particularly if Axiom's use of cagetories is different from
mathematical category and set theory - so much for the starting point I
had been intending to use ;-). Darn it, that would have made it so
nice - I could have read up on the research on set and category theory,
and (tried to) make a literate document containing both the human level
algebra foundations and the computer level algebra foundations.
Perhaps "understand Axiom's domain and category construction" should be
item #1 (or maybe 0) on our "conversion to Aldor" roadmap. Any attempt
that doesn't involve a firm understanding of that is probably going to
result in Massive Confusion, at best.

Agreed.

OK. If we're going with Aldor for sure that of course becomes much
less interesting.

Makes sense to me. I thought the logical cutpoint would be where the
"core" algebra logical framework was defined, but it sounds like that
might be sort of mixed up between knowledge in the SPAD compiler and
the algebra files? If I've understood that correctly I would say
that's the problem we need to attack first.

Agreed. Am I correct that the logical starting point is to identify
where the compiler ends and the math begins (whether it is set/category
theory or Axiom's domain and cagetory implementation or whatever) and
get the core parts documented and working on top of Aldor?
