Specialized implementation of PName: can be used for short Strings
that consists of at most 4 bytes. Usually this means 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)
