Comment(by davidloeffler):
Yup, this is annoying. The reason for this is that the {{{X.<y>}}} syntax
defines y to be the first element of {{{X.gens()}}}, but gens for number
field orders returns *module* generators, not *ring* generators (which
don't always exist for general orders).
It would certainly be nice to fix this, but it's not clear to me what the
best solution is.
