One of the most powerful features of Python are comprehensions. They make code shorter and more readable at the same time. We have list comprehensions, dictionary comprehensions, set comprehensions and tuple comprehensions.
I wonder, why not go further, and make Everything Comprehension? I suggest the following syntax:
for i in <all prime numbers>:
DataFrame.<delete all rows with negative values>
for f in <all Python files in the current folder>:
<run unit test on f to check if it works as expected>
if <np == p>:
<send email to Fields Medal committee>
As you can see, the code become shorter and more readable at the same time!
You may be reading this and thinking: well, there is a notable technical difficulty in implementing this feature. Yes, indeed, Python already uses < and > for comparison. But in the proposed syntax one can use a <is greater than> b for comparison, and backward compatibility can be ensured by writing <ensure backward compatibility>.
We definitely need the <ensure backward compatibility> feature. This will be very important to future Python proposals. Question: What happens if you do from __future__ import <ensure backward compatibility>? Does this create a timey wimey ball?
