Detect possible simplifications using walrus

[sam-s]

Current problem

Here is the code that should be flagged by a walrus checker:

foo = ....
if foo:
    ....

the better code is

if foo := ...:
    ...

Desired solution

there should be a "code review" checker that flags code where

• a variable is set and
• its value is immediately checked and
• is is not used if the check fails

Sound like https://pylint.readthedocs.io/en/stable/user_guide/messages/refactor/consider-using-assignment-expr.html, you need to activate the code style checker:

py-version=3.8
load-plugins=pylint.extensions.code_style
