Very good point. We *must* remember to make X.list() use the
deprecation warning system, and only remove it after 6 months. Could

For the OP, it was surprising that "lis
Maybe I missed the point here but after
R.=QQ[]
M=matrix(R,1,2,[x1+x2,x1*x2])
you can get at the entries like this:
sage: M[0,0]
x1 + x2
sage: M[0,1]
x1*x2
where the only non-obvious thing to a mathematician is that the
row/col indices start at at 0.
The list() discussion seems separate to me.
