Comment (by kcrisman):
Turns out that it's possible to get all variables used so far in Maxima
with `values`, and one could do a blanket `declare` on all of them. (Of
course, one might not want to do this to all of them...) Fateman also has
the following enigmatic response to me on the Maxima list.
{{{
I think the understanding of complex variables is at best spotty, and if
you want to do "a LOT" of
things with them you better check out exactly what Maxima does, and
perhaps even make it work
with names that have no special properties.
}}}
Anyway, I really don't want to go back to assuming things in Maxima on
every variable defined in Sage (or even every SR variable) but I think we
might have to go that way. Maybe there is a flag we could set as an
underscore attribute in the SR vars indicating whether it has been
declared complex in Maxima yet, which would be dealt with appropriately
for ones which aren't complex, or have been assumed real, etc. - i.e., the
''next'' time one went into Maxima, they would be in a queue that was then
declared complex. Not sure how hawkish that would be, but hopefully at
least not slowing down Pynac variables appreciably.
