Martin,

I don't know whether it is in fricas or not, but I have something on my wish list for fricas - namely the option for a / 0 = 0 for the field of real numbers, as is standard in Isabelle/HOL, and implicit for the pseudo-inverse in linear algebra.

Could this be engineered as a domain?

Regards,

Jalaluddin

OK, I'll wait to hear from you.

In the meantime I am working on a companion domain 'Lambda' which can be
coerced to and from the SKI combinator domain. I've also been thinking about a
third IntuitionisticLogic domain.

BTW: In the message containing first version of 1.1.2 news/relase notes
when I wrote about additions I meant additions to the notes.
Yes, I realised that, but I thought there may have been a small chance of
sneaking it in.
