Replying to [comment:4 kcrisman]:
> Just adding cdefs is, in my experience, a recipe for disaster.
That's true. One first needs to have a good guess what yellow code is most
frequently executed. %prun might indicate where the problem is hidden, and
the annotation indicates how to get rid of it.
> Also interesting about the prun. This is mostly just taken from the
complex plot stuff, but prunning (?) that shows just a couple calls to
complex intervals. I assume it is mostly happening in the `which_root`,
maybe {{{if abs(varia-root)<2/3}}}.
It makes sense to try that separately. I.e., %prun one call to
`which_root`.
> I don't like all the calls to `isinstance` and the polynomial ring
consructors, either.
Yes. They are irritating. I am rather sure that `isinstance` is called in
things like `sage.rings.ring.is_Ring` or so.
> Someone who understands how `fast_callable` constructs things better
might be able to help,
Sorry, `fast_callable` is a mystery to me.
