There is no need to keep full control under python, no.
However I feel that the first problems are purely algorithmic and they
don't need any new c++ function. If you want to debug easily it it's
probably better to use only low-level functions in C++ for the moment.
For instance a function which passes one body to a worker and insert it in
the right place together with interactions is probably just a few lines of
python.
When the entire thing works that function can be turned into a trigger,
then you use that trigger in another higher-level python function (which
will select what to pass based on intersections), which when it works is
turned into C++, and so on, recursively.
If you don't erase the python versions of each function it will lead to two
concurrent implementations in C++ and Python, which will be useful in the
long run.
Cheers
