I believe I understand it sufficiently well to say that it is safe and  
appropriate to use instead. I propose to change E-on-Java to replace  
the Nested* mechanisms (backwards compatibly, i.e. the .leaf() sugar  
and so on will still exist) with causes.

* What is the minimum Java version E-on-Java is intended to require?

* Do you have any reason to suspect that getCause() etc. may be less  
straightforward than it appears?

* Do you object to this proposed change for any other reason?
