Sorry, -1.
Is this really worth the hassle when you can write (more explicitly)
def my_fun():
raise NotImplementedError # todo
Python has grown steadily more complicated in its lifetime. Usually for
good reasons. But each additional feature adds to the learning curve
and the maintenance burden. New features have to be justified by
getting a consensus that the benefits outweigh the extra complexity.
How would you decide what corner cases such as these would do:
eval("...")
exec("...")
[ ... ][0]
... if x is None else y
return ...
and how would this affect the implementation of the compiler/interpreter?
Best wishes

In examples in the web very often we see unfinished or partial code,
where the ellipsis "..." is used in place of missing instructions.
Idea: make ellipsis used in that context throw an exception, reminding
the user that this code is work in progress.
The exception could be called ToDoError, or WorkInProgressError, or
simply EllipsisError, and could be derived from NotImplementedError.
```
def my_fun():
... # todo
my_fun()
> WorkInProgressError: Implementation of `my_fun` is not finished.
```
This change could break some code, as for now ellipsis in the middle
of code is silently ignored, but I don't think anybody seriously
relies on that behavior.
