Python allows programmers to pass additional arguments to functions via comments.
Now armed with this knowledge head out and spread it to all code bases.
Feel free to use the code I wrote in your projects.

Image transcription:
# First we have to import comment_arguments from arglib
# Sadly arglib is not yet a standard library.
from arglib import comment_arguments
def add(*args, **kwargs):
c_args, c_kwargs = comment_arguments()
return sum([int(i) for i in args + c_args])
# Go ahead and change the comments.
# See how they are used as arguments.
result = add() # 1, 2
print(result)
# comment arguments can be combined with normal function arguments
result = add(1, 2) # 3, 4
print(result)
Output:

Choosing lib
as the name for my module was a bit devious.
I did it because I thought if I am creating something cursed why not go all the way?
Regarding misinformation:
I thought simply posting this in programmer humor was enough.
Anyways, the techniques shown here are not yet regarded best practice.
Decide carefully if you want to apply the shown concepts in your own code bases.
This isn't standard python.
lib
is not in the standard library. Python also doesn't have any special variables where it stores comments, other than__doc__
which stores a docstring. If I had to guess,add
is reading the file/REPL via__file__
.Is __doc__ storing a comment or just a text string?
It's a string, although sometimes Python conflates the two. The recommended way to make a multi-line comment is to just make a multi-line string and just don't use it.
