Comment (by caruso):
Thanks!
I've tried to review my patch following your answer but I got a problem:
it seems that the specials functions `+` and `*` are not catched correctly
by the category framework (although it works for `__add__` and `__mul__`).
As far as I understand, the reason is that the method
`Element.__getattr__` is not called in these cases (and, as a consequence,
the methods in `category().element_class` are not examined).
I don't know if it is supposed to be a bug; if it is, I can open a new
ticket about it.
In the attached patch, I've implemented a dirty hack (cf. lines 195-198)
to get around this problem and make additions and multiplications of
Newton polygons work correctly.
