You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: flatten_methods.rb
    path of file: ./repos/sorbet/test/testdata/infer
    
    the code of the file until where you have to start completion: # typed: true

class Parent
  extend T::Sig
  sig {params(x: Integer).void}
  def self.takes_integer_static(x)
    
  def self.takes_integer_static(x); end

  sig {params(x: Integer).void}
  def takes_integer_instance(x); end
end

class Child < Parent
  takes_integer_static def self.outer_static # error: Expected `Integer` but found `Symbol(:outer_static)` for argument `x`
    takes_integer_static def self.inner_static; end # error: Expected `Integer` but found `Symbol(:inner_static)` for argument `x`
  end
