It comes up every once in a while.  Nobody has made any attempt
to actually include it in SAGE yet though.   What does it do
that SAGE doesn't already do?  My impression is that it's integration
capabilities are less sufficient than Maxima's.  Also, my impression
is that yacas is meant to be used via an interpreter, rather than
as a C++ library.

The email linked there is an interesting read.  I guess what I found
most striking about it was the lack of discussion or desire for feedback
on the description of the direction in which yacas would go.  (Maybe there
aren't many developers, or the discussion was private?)

I would be very happy to be very enthusiastic about yacas, but I'm not
based on the very little I know so far.  It would
be great if somebody could write to me or to this list explaining
the point of yacas and how yacas could be helpful for SAGE.
Thanks!  E.g., does yacas do anything in particular very very very
quickly?   Does it implement algorithms not in SAGE already?
How could it help with SAGE's main goal, which is to be a clean
unified well structured mathematical software system that is a viable
alternative to Mathematica, Maple, Magma, and MATLAB?
