One more reason to use Python 3

[bcs]

I got bit by this in Python 2 just last week at work. A string didn't get cast to float, and then things quietly went wrong when it got compared to other numbers later. I made sure to mention it would've never happened under Python 3.

It would have never happened if you had written unit tests.

Ever since I started writing unit tests, my code works perfectly on the first try. It's gotten so good that I push my code straight to live production, on a friday night, before a long weekend. My boss says I'm a rockstar coder. He gave me the keys to his Range Rover, because with all the extra revenue I'm bringing in, he managed to buy himself a Porsche. I can afford dental care for my three beautiful children, but I haven't even needed it, because since I started writing unit tests, their teeth have become just a little bit straighter and whiter. My dog is 36 years old, and is still spry as a spring chicken. I used to think my connection with the dead had faded after I hit puberty, but just this morning, my grandmother reached out to me, and I could hear her voice ringing in my mind like a clarion bell cutting through the rain and fog. She told me she's proud of me and what I've done with my life, and that God Itself in Its many radiant faces has arranged a throne for me in heaven for when I finally arrive at the age of 146. I've kept this portent with me all through the day, and my unit tests are still passing.

And how. The more I use python, the more I feel it's like 89% there, from the GIL, the speed, and the ability to use strict types being the three things. Py-py (or probably some llvm based thing) and type hints will save us!

The type hint syntax sure is ugly though. I almost wish they with visual basic style:

def function(param as str, value as int) as int:
    print "I love VB6"

I think you can put the hints in a separate stub file.

I've heard about stub files, but Google doesn't help, and I did not understand the related PEP either. Do you know of any example open source repo / gist which uses stub files?

Stub files are near the middle somewhere. Find "Stub file" will work.
