Comment(by malb):
The patch applies cleanly and doctests pass.
I'm still not happy with the interface:
{{{
#!python
sage: P.<a,b> =
PolynomialRing(GF(32003),order=TermOrder(Matrix([1,2,0,3])))
sage: P.term_order()
m(1,2,0,3) term order
}}}
This uses the non-standard "m(...)" representation which I would avoid.
I'd be happy with either "M()" (Singular notation) or "Matrix term
ordering with matrix ..." or so.
Also, the "m()" notation is allowed but shouldn't.
{{{
#!python
sage: P.<a,b> = PolynomialRing(GF(32003),order='m(1,2,0,3)')
}}}
I understand that this is a typical paint-the-bike-shed scenario and in
particular a question of choice. Still, I think we shouldn't invent more
ad-hoc string notation when (a) there is an established notation and (b)
we have a much nicer object oriented way of constructing term orderings.
However, since this isn't really that big of a deal, I am okay with being
overruled by some other referee who disagrees.
PS: Apologies for taking so long to revisit this ticket.
