It was born in the LISP environment, where atoms were "interned on the
OBLIST" to make them unique.

Just the element types, IMHO.  This is very easy to expose as Strings
for almost any kind of parser.  If you want more, do it yourself.

It certainly can be, but the parser is already doing it, and why
reinvent the wheel?
