| -- 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). |
