Raymond Hettinger added the comment:
As soon as the trunk opens again, I'll add Nick's version to the itertools
recipes section.
I'm disinclined to add it directly to the itertools module as a native C
function for several reasons:
* The problem solved isn't that common (very little of

David said, now I have a place in the non-test email code where using this
would lead to easier-to-read code. IMO, this is telling. The bar is
higher than I would have used this one time. That doesn't make it worth
having to learn and remember.
I will

Hynek, thanks for your suggestion. I would like to mull it over for a while
before chiming in.

Hynek Schlawack added the comment:
Well that's the point: it's extremely handy but simple. I wish Raymond would
pronounce on this. I can keep using the PyPI version for all I care, so I'm
not going fight for it. But with one exception there seems to be an agreement
that it would be a very

For what it is worth, I am currently writing some email tests and it would
certainly be convenient to have this. Of course I *can* define it locally in
the the test file.

Hynek Schlawack added the comment:
So I wanted to provide a first patch to move the discussion on and realized
that itertools appears currently to be completely inside of
`Modules/itertoolsmodule.c`. :-/
Any volunteers? :)

Serhiy Storchaka added the comment:
How large will be a C implementation of this one-line function?
I'm still -1 for polluting the itertools module with trivial combinations of
existing functions.

The solution is to move the current itertools to _itertools and have a
companion itertools.py.
Serhiy Storchaka added the comment:
Looks as too much work for too small gain (and I'm suppose the total gain is
negative if we count all costs).

I fully agree.

I assume what's missing now is a permission from Raymond to mess with his turf?

Antoine Pitrou added the comment:
I would like to chime in and say that the fact that the functions exists in SQL
(and possibly Lisp, Snobol and PHP) sells me on the idea!
Okay, only joking, but I do think this is a useful addition.
first_true should be its name, but itertools already has a

Nick Coghlan added the comment:
I concede Tim's point about itertools already using underscores where it
improves readability of a name :)
So, the latest state of the proposal is to add the following, preferably
directly to the module, but at least as a recipe in the itertools docs:
