This thing doesn't work with numpy arrays. That's why I am using `len` and
that's why I had to write the ugly patch earlier.
The documentation of point2d is clear enough with regard to its input:
{{{
Point takes either a single tuple of coordinates or a list of tuples.
}}}
But the way the function is written you can pass it either a list of
tuples/list or a tuple of tuples/list, or with this patch a numpy array.
