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: dependency.rb
    path of file: ./repos/artichoke/artichoke-backend/vendor/ruby/lib/rubygems
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
##
# The Dependency class holds a Gem name and a Gem::Requirement.

class Gem::Dependency
  ##
  # Va
    
  def to_spec
    matches = self.to_specs.compact

    active = matches.find {|spec| spec.activated? }
    return active if active

    unless prerelease?
      # Move prereleases to the end of the list for >= 0 requirements
      pre, matches = matches.partition {|spec| spec.version.prerelease? }
      matches += pre if requirement == Gem::Requirement.default
    end
