class String

  # Converts a string to module name representation.
  #
  # This is essentially #camelcase. It also converts
  # '/' to '::' which is useful for converting
  # paths to namespaces.
  #
  # Examples
  #   "method_name".modulize    #=> "MethodName"
  #   "method/name".modulize    #=> "Method::Name"

  # Rails definition:

  #    gsub(/\/(.?)/){ "::#{$1.upcase}" }.
  #    gsub(/(?:_+)([a-z])/){ $1.upcase }.
  #    gsub(/(^|\s+)([a-z])/){ $1 + $2.upcase }
