Hi,

I will post the solution tomorrow. Clumps are not yet wrapped in python, 
but it is fairly easy thing to do: function taking list of bodies and 
appending those as clump to the body container.
For the obscurity of syntax, there are 2 points.

1. Creating instance of a class. It used to be obsucre like 
StandAloneEngine("PersistentSAPCollider",{'haveDistantTransient':True}). 
I introduced new syntax for it (like a month ago), which is much more 
pythonic: PersistentSAPCollider(haveDistantTransient=True). Have a look 
at scripts/simple-scene.py, I think it is more readable now.
2. Accessing attributes. You have to use object['attribute'] notation to 
get real (serializable) attributes. It would be best to use 
object.attribute instead, but I am still investigating how to do it, as 
there are non-c++ attributes that are accessed in this way (like methods 
or object.name and so on).
