Thank you for your answers. I was actually aware of hidden methods being
accessible from inside the class, but I somehow gave a bad example... I
note the advices that
1. Having to do manual mangling probably reveals some bad
structuration, and
2. Instead of do manual mangling, one can usually add a relevant
method in the relevant class.
Thanks!
Bruno
P.S.: Well, for number_of_terms in Polynomial_generic_sparse, there is
now #18617 ;-)

Since this is a class where the attribute is defined, you don't need
to mangle anything.
Otherwise, I would say that manual mangling is bad. Two solutions:
(1) rename the attribute __coeffs to _coeffs
(2) make an accessor function
def number_of_terms(self):
return len(self.__coeffs)
