Comment:

 Has this been tested on various systems?  The kind of output like
 {{{
 {0: [0.0, 1.0], 1: [0.866025403784, -0.5], 2: [-0.866025403784, -0.5], 3:
 [0.433012701892, -0.25], 4: [-0.288675134595, -1.85037170771e-16], 5:
 [0.288675134595, 3.70074341542e-17], 6: [0.144337567297, 0.25]}
 }}}
 has a tendency of being quite system-dependent because of precision
 issues.

 In any case, if all you did was add an option, why did the output change?
