That's what I did so far but it is not always possible.

The comment in line 98  in IntersectionLoop.cpp says:

// arguments for the geom functor are in the reverse order (dispatcher would 
normally call goReverse).
// we don't remember the fact that is reverse, so we swap bodies within the 
interaction
// and can call go in all cases

In fact, it seams goReverse is never called because bodies are swapped before. 
So maybe we can get rid of it???
