I have just played with this, just very little... what I'd like to know  
more about is why the 3 ways of using Modeling.dynamic? It is not clear  
to me... and:
- it seems more code complications, that someone must maintain ;(
- more documentation, that someone must write, and maintain ;(
- more documentation, that someone must understand ;(
- not pythonic... as "there is no clear and obvious way to do it"...

When you get the time, could you say a little more about the rationale  
for these 3 ways, and, if these ways are not explorative and temporary  
(will "standardize" on one way in the future...), what are the  
advantages of one way over another, and when would you use one and not  
the other?

These problems apply only to the first way, or to all three?
