ok, I will do it.

ok, I will do it.

do you think?
The original method is {{{point}}} and at the end of the model there is a
{{{points = point}}} line, so I guess we have to support the 'singular'
case of only one point in {{{xydata_from_point_list}}} I'll have a look
into the failing case {{{point(1)}}}.

What do you mean by 'used to work'? I tested {{{points(complex(1j))}}} in
cloud.sagemath.com (v6.10) and it doesn't work.
> And ideally, numpy complex numbers should also be supported. You would
better use `numbers` as adviced in [comment:8 comment:8].
ok, ok, ok :-) I'll give it another try, last time I tried I wasn't able
to make it work.
