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: signature_service.rb
    path of file: ./repos/steep/lib/steep/services
    
    the code of the file until where you have to start completion: module Steep
  module Services
    class SignatureService
      attr_reader :status

      class SyntaxErrorStatus
        attr_reader :files, :changed_paths, :diagnostics, :last_builder

        de
    
      def type_name_from_decl(decl, set:)
        case decl
        when RBS::AST::Declarations::Class, RBS::AST::Declarations::Module, RBS::AST::Declarations::Interface
          set << decl.name

          decl.members.each do |member|
            if member.is_a?(RBS::AST::Declarations::Base)
              type_name_from_decl(member, set: set)
            end
          end
