Comment (by vbraun):
I'm a bit confused by the code... the !DifferentialRing isn't really a
ring in the Sage sense (with elements that have ring operations). Am I
missing something? The starting point should be a proper differential
algebra ring, e.g.
{{{
sage: R = DifferentialRing(vars=['x'], functions=['f'])
sage: x = R.var(0)
sage: f = R.function(0)
sage: (2*x*f).parent() is R
True
}}}
and perhaps slightly extend the preparser to allow
{{{
sage: R.<f(x)> = DifferentialRing()
}}}
