This is probably hard. It would increase our potential user base, though,
as well as make it possible for people to use Sage in virtually any
college course very easily (with the exception of most geometry courses,
but a Geogebra plugin would do that).
Examples from the recommended (not currently installed) MASS package; one
can certainly come up with one's own examples, this just shows what isn't
supported and the current error messages.
