Sorry left too early, the slides are updated with the fixes suggested,
thanks everyone.

For me the biggest problem is still:
- to find some more interesting example that is easy enough to explain
- to find a better order in which explain things, to tell a clear story in a way

>>> slide 9:

>>>         body(it)

>>> slide 21:
>>> from itertools import count, ifilterfalse
>>>
>>> def divided_by(p):
>>>     return lambda n: n % p == 0
>>>
>>> def primes():
>>>     nums = count(2)
>>>     while True:
