String refinements

string_extensions.rb

module StringExtensions
  refine String do
    # "Brute force" underscore the string.
    # Removes any non-alpha characters for clean symbol ready strings.
    def brute_underscore
      self.gsub(/::/, '/').
      gsub(/([A-Z]+)([A-Z][a-z])/,'\1_\2').
      gsub(/([a-z\d])([A-Z])/,'\1_\2').
      gsub(/([\\][\"])/,'').
      tr('-', '_').
      tr(' ', '_').
      squeeze('_').
      downcase
    end
  end
end

I'm sure that this doesn't really do everything it claims to yet, but I will add the functionality once I identify its failings... I also need to add some tests and perhaps put this into a Gem/repo.
