Of course, it's not a toy. To a large degree, it's a large collection of
existing software, "Gentoo of maths", with its own package system. And it
includes maxima, fricas, pari/gp, gap, singular, R, and many other
systems. They are all integrated together to some degree, so, sage is
somewhere in between a monolythic CAS (maxima, reduce, fricas,...) and
just a collection.
It would be interesting to make reduce one of its packages, too.
