(Yes, Yes, Yes, Yes, No, No, continuous_bijection_inverse_continuity_required)

Compute both directions rather than assuming either one from the family name. A discrete-to-indiscrete continuous bijection can have a noncontinuous inverse; reversing its direction interchanges the two continuity obligations.
