------------------------------+----------------------------
It seems like the ring attribute of vector() is ignored in some cases.
The following test should pass, if I understand correctly the use of the
vector constructor:
{{{#!python
import numpy as np
v = np.asarray([0.5,1])
vv = vector(RealField(rnd='RNDU'),v)
assert vv.parent().rounding_mode() == 'RNDU'
}}}
Instead, vv is created with ring RDF rather than the correct one, so the
assertion fails because it cannot access rounding_mode().
