Comment (by ncohen):
Yo !
> Ah, true. This could also start with `rank_fcn=[None]*self.order()`
instead of `rank_fcn={}`, but the current code seems to be cleaner.
Right again. And I could have turned the 'if x in rank_fcn' into 'if
rank_fcn[x] is Null'... Stupid me.

status.
I hope that you do not mind: I am going to add a commit in a second to do
that properly with a list in the function too. Not very important, but
worth doing anyway.
