Improve class method printing

[AlanFoster]

Rails in particular has a lot of class methods within its API. I'm not massively opinionated here, but perhaps the convention should be to drop brackets on method calls within class bodies

Input

class MyClass
  helper :all
  before_action :hello_world
  include FooBarBaz

  def self.foo
    puts "foo"
  end
  private_class_method :foo

  private_class_method def self.bar
     puts "bar"
  end
end

Current output

class MyClass
  helper(:all)
  before_action(:hello_world)
  include(FooBarBaz)
  def self.foo
    puts 'foo'
  end
  private_class_method(:foo)
  private_class_method(def self.bar
    puts 'bar'
  end)
end

Expected Output

Brackets are dropped from method/command calls within the class body

class MyClass
  helper :all
  before_action :hello_world
  include FooBarBaz

  def self.foo
    puts 'foo'
  end
  private_class_method :foo

  private_class_method def self.bar
    puts 'bar'
  end
end

Hey, we do drop parens when we should like for puts etc.
we can add more method names where parens are not required, or we can default to no paren and add it as an option.

Yip, all sound good - I'm sure we'll get the right balance here 🤞

There's also a bunch of nice examples within Rubocop too - https://github.com/rubocop-hq/ruby-style-guide#classes--modules

How about printing parens if the call breaks, if there is a nested call, or if there are 3 or more parameters?
