But they wouldn't!  Why would you think that any of your work was lost when you
install axiom after having installed friCAS?  The only difference is, if the
names wouldn't change, they wouldn't need to adjust paths they currently don't
even know about.

If it were a single symbol, ok.  But it's not.  What about the wikimedia plugin
for axiom?  What about the TeXmacs interface?  Do you really want to maintain

axiom.el, fricas.el, openaxiom.el,,,
axiom.php, fricas.php, openaxiom.php?

It seems to me that such a change would rather be a hindrance to cooperation
than making cooperation easier.  It's quite the same with IssueTracker.

Really, if this mess stays the same, it will drive me mad.  Already I have to
include 3 email lists if I want to say something all axioms should care about,
which is the case most of the time, since I'm working only on the algebra
level.  Cooperation in this manner is for me such a nuisance, that I'd rather
stop it.

In fact, as a mathematician, I often use the same symbol for different things,
and let context decide.  I do so as an axiom programmer, too.  For example,
"eval" can refer to roughly 38 operations, some even having different number of

I cannot understand why you want different names for the same thing!
