[Axiom-developer] Lisp representation of Union, Record, etc.

[daly]

As these discussions proceed I'm trying to write up the details we
discover in the developer notes so other people can follow when these
things come up again. I'd like make a whole section devoted to a
couple interesting domains (e.g. Integer, DHMATRIX), peel them open
completely, and show exactly what the fields mean, how the interpreter
uses them, where the data comes from, how the compiler constructs the
domain, etc. However, caching these discussions is an epsilon move
closer to that goal. With pictures, circle and arrows, and a paragraph
on the back explaining each one. :-)
