Comment (by vdelecroix):
And this is not the only wrong thing with interfaces. The default
implementation of conversion between Sage and the interfaces etc relies on
string representations and global variables... which is of course
unreliable
{{{
sage: R = PolynomialRing(ZZ,('x','y','z'))
sage: p = 3*R.0*R.1 + R.2^3
sage: pari(p).sage()
Traceback (most recent call last):
...
NameError: name 'y' is not defined
sage: y=2; z=5
sage: pari(p).sage()
}}}
or
{{{
sage: pari(ZZ).sage()
<built-in function IntegerRing>
sage: pari(RR)
RealFieldwith53bitsofprecision
sage: pari(RR).sage()
Traceback (most recent call last):
...
NameError: name 'RealFieldwith53bitsofprecision' is not defined
}}}
