With Elixir 1.20 on the horizon, many projects are about to discover that they have a lot of unnecessary require Logger lines throughout their codebase.

mix styler.remove_unused will automate the removal of those unused require: statements, alongside any unused import: and unused alias: wa...

Two new standard-library pipe optimizations

• enum |> Enum.map(fun) |> Enum.intersperse(separator) => Enum.map_intersperse(enum, separator, fun)
• enum |> Enum.sort() |> Enum.reverse() => Enum.sort(enum, :desc)

And Req (the http client library) pipe optimizations, as detailed below

Rewrite single-clause case statements to be assignments (h/t 🤖)

# before
case foo |> Bar.baz() |> Bop.boop() do
  {:ok, widget} ->
    x = y
    wodget(widget)
end

# after
{:ok, widget} = foo |> Bar.baz() |> Bop.boop()
x = y
wodget(widget)
