Comment (by dlucas):
Hello,
It seems that your changes actually broke something...
If you look in `src/doc/en/thematic_tutorials.coding_theory.rst` lines
614-619, you'll see that the following input:
{{{
sage: F.<a> = GF(3^2,"a")
sage: pts = [0,1,a,a^2,2*a,2*a+1]
sage: C = codes.GeneralizedReedSolomonCode(pts, 4)
}}}
is not accepted anymore.
Furthermore, the following:
{{{
sage: F.<a> = GF(3^2,"a")
sage: C = codes.GeneralizedReedSolomonCode(F.list()[:6], 4)
}}}
is accepted but `sage: C` returns `[6, 4, 3] Generalized Reed-Solomon Code
over Finite Field of size 3` and the ''over Finite Field of size 3'' looks
weird to me.
