-- This section lists the various cases of generated names which are
-- built from existing names by adding unique leading and/or trailing
-- upper case letters. In some cases these names are built recursively,
-- in particular names built from types may be built from types which
-- themselves have generated names. In this list, xxx represents an
-- existing name to which identifying letters are prepended or appended,
-- and a trailing n represents a serial number in an external name that
-- has some semantic significance (e.g. the n'th index type of an array).
