Hello,
The cache part is cool!
I am not confident of having everything switched into Cython. It is much
harder to debug and can also makes things slower. Especially with
functions like `wilson_construction`, `OA_n_times_2_pow_c_from_matrix`...
Why not only switch to C for the cache part? The function
`orthogonal_array` might also move and we might also recreate the
`orthogonal_array_available` from #16875.
In the function `orthogonal_array`, I do not remember what was the point
of the variable `may_be_availale` in `orthogonal_arrays`... And I am
confused by the way it is used: if it is `False` then there is no need to
go further (but it concerns only the case when `existence=False`).
Vincent
