  If the objects are implemented as a C/Java extension type, it should
be plenty fast.  A 100% Pure Python implementation can be a fallback
if the extension isn't available.

  Very much.

  And the convenient tuple unpacking could also be provided using the
object approach; the objects can easily implement the sequence
protocol.
  I'd be willing to write a C implementation of the object version if
that's the API we decide on, but I'd also be fine with the third
option.
