--- Semi-public internals. Most users should not need to use this
+-- A module containing private 'Text' internals. This exposes the
+-- 'Text' representation and low level construction functions.
+-- Modules which extend the 'Text' system may need to use this module.
+-- You should not use this module unless you are determined to monkey
