I'm starting this implementation and I'm facing an issue with "context".
I would like also to put context in the transaction but there is some
problems:

- the context has been most of the time put as last keyword (except for some
  methods like search). So it is complicated to find it in the args list.
  But we can change those methods and put the context as first argument for
  external calls (this will change the API).

- if we remove the context from the methods then the signature of each method
  will be different between external call and internal. It is already the case
  with cursor and user but one goal of this change is to fix it.


So is there someone knows an other framework that has the same context-like
behavior and how they solve it?

Or perhaps the solution will be to drop the context for a better solution as
I always found it is not an elegant one.
