Comment (by jj):

 Hi

 Just an idea:

 Shouldn't it be possible to define/implement Dirichlet series by
 specifying a function
 (from Z/ideals/whatever) for their coefficients?

 I guess that would require some base class (which ideally would
 accept/parse/recognize
 functions from Z/whatever) for the coefficient functions.
 I would do parsing tasks, printing(!) of functions, arithmetic
 operations/dirichlet
 convolutions/etc... (Completely) multiplicative functions would be a
 "nice" subclass.
 Ideally the implementation would at least support basic Dirichlet series
 example.

 Again: Just an idea (for either an extension or a new
 implementation/ticket).

 Regards,
 Jonas
