/**
 * Specialized implementation of PName: can be used for short Strings
 * that consists of 5 to 8 bytes. Usually this means relatively short
 * ascii-only names.
 *
 * The reason for such specialized classes is mostly space efficiency;
 * and to a lesser degree performance. Both are achieved for short
 * Strings by avoiding another level of indirection (via quad arrays)
