rbs prototype rb vs. class << self

[palkan]

Example code:

# a.rb
class A
  class << self
    attr_reader :foo

    def bar
      "baz"
    end
  end
end

Generated signature:

$ rbs -v
rbs 0.19.0

$ rbs prototype rb a.rb

class A
  attr_reader foo: untyped

  def self.bar: () -> "baz"
end

The signature declares attr_reader for the class instances, not the singleton.

(Also, we currently don't support self attr_reader/writer, right? Or am I missing something)

I think the improvements in the latest version 0.20.1 would help. (#502 and #505)
