I’m quite happy with the new mix format task, except for my Ecto queries

Currently mix format would convert

query = from u in User, where: is_nil(u.team_id)

to

query = 
  from(u in User, where: is_nil(u.team_id))

and I’d like it to be

query = 
  from u in User, where: is_nil(u.team_id)

I looked at the docs, and there’s an option to make the formatter skip some parens, but I’m either doing it wrong or it’s not meant to work with 3rd party libs. Here’s my .formatter.exs:

[
  inputs: [
    "mix.exs",
    "{config,lib,test}/**/*.{ex,exs}"
  ],
  export: [
    locals_without_parens: [from: 2]
  ]
]

Any ideas, anyone? Thanks!
