Comment:
I guess I'm bad news' harbinger again, as I noticed the following:
{{{
sage: PR.<x> = GF(7)[]
sage: M = random_matrix(PR, 5, 5)
sage: type(M)
<type 'sage.rings.polynomial.polynomial_zmod_flint.Polynomial_zmod_flint'>
sage: type(M.row_reduced_form(transformation=False, old_call=False)[0, 0])
<type 'sage.rings.fraction_field_FpT.FpTElement'>
}}}
So it seems that the actual implementation messes with the type of the
elements in the matrix, which is never a good thing...
