[snip long interesting post]

Martin, 

I've only halfway followed this thread, as
I'm not 100% sure in what sense people are 
using the term "generator"... if it's in a
pure Python sense, well, my knowledge of 
Python is very limited.

Why don't you read the post I made 
back in August and see if you think
there's any connection...

The thread is entitled "Super-iterator? (long)"
and starts at http://ruby-talk.org/46337

I was attempting to solve three or four
problems at once (some of which may be
non-problems to other people). One of
these was the lack of "on-demand" iteration
which as I understand it may be the same 
as generation.

Let me know your thoughts...

Thanks,
Hal Fulton
