Comment (by ncohen):
Yo !
> I like much better the interface now!
Well, I have a lot of things to write when this will be reviewed. Like the
functions to get all n such that there exists an `OA(k,n)`, and stuff for
incomplete orthogonal arrays too that I need for yet other applications of
the Brouwer van Rees construction.
All the stuff that I cannot write when everything is done through the same
function.
> In `OA_build` the argument `resolvable` is not used (and not tested).
Oh. Right. That's because I had created a "build_resolvable" function at
some point in the interface, and did not add it in the end.
> Why do you still allow `k=None` in the function `orthogonal_array`? It
would be simpler/cleaner if it was only managed by `largest_available`.
No?
It depends on you. I hate the very principle of backward compatibility,
but that's why it is there, because the guys who call
`designs.orthogonal_array` and will persist in doing so for a year even if
it displays a warning need to be able to call it anyway, or so I am told.
When this thing will not be deprecated anymore this will only be internal
code and we will be allowed to remove whatever we want whenever we want.
