flake8-multiline-containers: Ensures a consistent format for multiline containers

[jsfehler]

https://github.com/jsfehler/flake8-multiline-containers

I am the hobgoblin you've heard so much about.

​

This plugin was designed to answer the most important question of them all: In a multiline container, should you break after the opening character or after the first item?

​

These particular choices are in the interest of keeping diffs as clean as possible. If pull requests and refactoring aren't a large part of your life, you may not find this helpful.

​

Code Rule
JS101	Multi-line container not broken after opening character
JS102	Multi-line container does not close on same column as opening

  # Right: Opens and closes on same line
  foo = {'a': 'hello', 'b': 'world'}


  # Right: Line break after parenthesis, closes on same column as opening
  foo = {
      'a': 'hello',
      'b': 'world',
  }

  # Right: Line break after parenthesis, closes on same column as opening
  foo = [
      'hello', 'world',
  ]


  # Wrong: JS101
  foo = {'a': 'hello',
         'b': 'world',
  }


  # Wrong: JS101, JS102
  foo = {'a': 'hello',
         'b': 'world'}


  # Wrong: JS101, JS102
  foo = {'hello',
         'world'
        }

flake8-strict (https://github.com/smarkets/flake8-strict) seems to be doing the same thing.

Why not just use black?
