Comment (by aschilling):
> @Anne: I've run some benchmarks (which show that caching the coercions
to all of the h, e and p bases is a lot better than caching only the one
to the h basis). But they don't mean very much since Sage, in the absence
of a direct coercion, looks for a compound coercion by depth-first search
(which can be, and is in my case, extremely slow). I was too lazy to
manually register 2-step coercions, so I went a different way and gave the
user the freedom to decide what coercions to cache.
Darij, could you post the results of your benchmarks?
