Hi Jeroen,
Replying to [comment:10 jdemeyer]:

(9,x),(a,b,c,d,e,f),(M((1,2,3,0)),wp(2,3),lp)')

That is very strange. I can not imagine that my patch introduced that bug:
It changes the conversion from Singular to Sage, but it should not change
Singular itself (and what you get in your example is an error from
Singular, not from the interface).
Hence, I wonder whether my patch has ''introduced'' or ''uncovered'' that
bug.
Can you test on marks and t2 with unpatched Sage whether the line
{{{
sage: singular.eval('ring r1 =
(9,x),(a,b,c,d,e,f),(M((1,2,3,0)),wp(2,3),lp)')
}}}
fails?
