Comment (by ncohen):
Oh. I see. Then, that's because if you cache the output of a function and
that this output is mutable, there is no certainty that users will not
change the content of the cache by modifying the result returned by the
function.
That's why I was forced to convert to "tuple" the output of
`orthogonal_array` in #16347, which I totally hate. But I will rewrite
this to only cache the boolean values, I will implement this manually as
soon as all the dependencies are reviewed.
That's also why it is painful to not be able to cache only what you want.
