Changes (by SimonKing):
* status: needs_info => needs_review
Comment:
I suggest that we leave stuff as it is now, so that it can be merged and
we can build on top of it. Therefore, I revert it to "needs review".
If I am not mistaken, `SCA` is a special case in Singular anyway, and it
is a huge difference whether one works in an `SCA` or in an isomorphic
general g-algebra quotient (Oleksandr, could you tell how the ring should
be created in this case? I guess the function `SCA` in the patch does not
do the right thing).
I believe that there should be a sub-class of `NCPolynomialRing_plural`
for general quotients of g-algebras, and then a sub-sub-class for SCA that
uses the specialised implementation from Singular. But that should be on
#11878.
