If I understand correctly, in the above implementation I cannot
define firstly a (non-oriented) body, and then build, on top of it,
two bodies with opposite orientations. The point is, I want
both oriented bodies to share the same base Body object.

The above comments apply here, too.
In what concerns other suggestion, about Python language,
I shall do my best to understand them and apply them.
