As we integrate OEIS sequences and formulas, it would be very useful to have operators that work on entire sequences, e.g.
1. `cumsum(A000040)` starts at index 0 (one earlier than A000040) with val…

There are other packages for handling exact / rational arithmetic that we can try out / show off in examples.
Alternatively, using high (fixed) precision integers could improve performance by a lot

It would be useful to have a Decimal object that works similar to Float but works with base-10 arithmetic. It can use the standard library `decimal` library as a backend, to do all the hard work, simi…

1. faster creation of new Laurent polynomial via a `cdef _new_c` method
2. Make rich comparison compatible with polynomials
3. make Laurent polynomial complient with coercion for `/` so that the res…

Can TryFrom be implemented as well as FromPrimitive? This would make it easier to make conversions using `.try_nto()`.
I would further propose to allow performing arithmetic between rationals and f…

Whilst I only envisaged porting the P, N, and Z arithmetics from Coq, it might be nice to go for full-on completion and port QArith too. I'm not sure what the type should be, but probably something li…

The arithmetically normalized coefficients of this L-function
http://beta.lmfdb.org/L/ModularForm/GL2/Q/holomorphic/1041/2/a/a/1/1/
lie in Qsqrt5. But on the L-function home page those are only …
