Comment (by ncohen):

 Hmmmmm.... I'm sorry to say this but I read this patch 3 times, on three
 different days (with long intervals in between), and each time it made me
 very angry.. There's something like 1500 lines of code in there whose role
 is to do :
 {{{
 get_something()
     return self.backend.something
 set_something(x)
     self.backend.something = x
 }}}
 each time checking that the backend exists, and with doctests.. Honestly,
 we have to find a way around this. 1500 lines of code.Including doctests,
 of course. 1500 lines.

 I'll walk a bit and go eat something to change my mind, then think about
 it again.
