Comment (by darij):
Done!
@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.
In other news, this patch probably conflicts with every other patch that
edits symmetric functions -- sorry.
