Why this may be controversial: today someone could be calling
|'||np.array(..., copy="never")', which would call| '|bool("never")',
which would evaluate to 1, and would end up| doing the exact opposite of
never. So their code is wrong, and they do not know it but are used to
the error. If we change this, it would silently fix their code to do
what they intended.
Is that a correct reading of the problem?
If so, I am in favor of the proposal to use string options in addition
to boolean options.
