This might best, but with circles I guess I would have expected to wrap around (mod arclength). > This is what [Gary] wanted: > x, y = circle.at(0.) > x1, y1 = circle.at(0.5*circle.arclen()) > because the standard parameterisation is in arclength. Suggestion: a convenience method 'at_degress' or 'at_radians' for circles. (Might be nice for arcs too ...)
