I can't really do justice to this topic, so I'll settle for quibbling today ...
I want to discourage cruft. The "block" construct isn't needed, and
even if there were multiple expressions, in the absence of local variables
you can write just (e1, e2, e3) . It's hard enough to understand
what's going on without extra clutter.
Aside from that, this question of representing multiple values is
very interesting and I'm pretty sure we could figure out a way to
handle it in a way that is both useful and well-founded. It seems likely
that multiple values could be represented as sets. We probably
have to strengthen Maxima's ability to handle sets to make it work.
