Comment (by rbeezer):
{{{.kernel()}}} gives a vector space, not a matrix space.
{{{.matrix()}}} provides a matrix whose rows are a basis of the vector
space.
{{{.list()}}} for a matrix might gives the rows, or something (unchecked).
"Every element k in K.list() gives "0" vector (M*k)." As it should be.
But your ticket implies you think the converse should be true. This would
be impractical for matrices over an infinite ring.
Did you try listing the actual vectors of the kernel itself, not the
matrix? Not sure if that will behave as expected or not. Perhaps so?
