I definitely agree with that sentiment, with beginners I don't even talk
about function defaults at first, and when I do, it's when we have already
have a talk about mutables so I can just say that you almost never want a
mutable default but rather use None as a sentinel. It's not that hard and

It's supported with several syntaxes in macropy (
https://pypi.org/project/MacroPy/) but I remember seeing it in a more
serious (for lack of a better term) package t

Hi,
All apologies if it has been clarified earlier, but if you dislike nested
method calls what is wrong with operating on generators as in
```pycon
>>> itr = (i**2 for i in range(8))
>>> itr = (i-1 for i in itr if i > 0)
>>> list(itr)
[0, 3, 8, 15, 24, 35, 48]
```
This covers chains of maps and
Hi,

Even if you think this is clever or funny, are you absolutely sure you
needed to share it with the subscribers to this mailing list?

Hey,
You can always do `itertools.chain.from_iterable(zip(iterable,
itertools.repeat(sep)))` but I agree that it is verbose.

For simple cases such as `[y + g(y) for y in [f(x) for x in range(10)]]`,
I don't really see what the issue is, if you really want to make it shorter,
you can ``[y + g(y) for y in map(f,range(10))]` which is one of the rare
case where I like `map` more than comprehensions.
For more complex case, j
