Comment (by ncohen):
> It is not only about conversion. !ProjectivePlaneDesign is buggy: there
is crazy argument "type" which makes specification a bit more complicated:
> - if type is None: do what you know is the best and return '''a'''
projective plane
> - if type is something: do whatever the construction tells you and
return '''the''' corresponding projective plane
This ticket is no place to fix that.
> Now if you incorporate the `who_asked` feature. It becomes crazy! I feel
like `type` and `who_asked` are rather incompatible. To my mind, we should
simply remove `ProjectivePlaneDesign` and have different functions (which
raise only `ValueError` on bad entries) for each kind of projective planes
we know about.
Vincent, the "type" keyword is not even USED. Remove it if it makes it
easier for you.
