Symbol is a sub-class of String. Whereas there may be two different strings
with the same sequence of characters, there can only be one symbol with the
same sequence of characters. This is useful when using names as the basis for
lookup (in tables). For example XMF ensures that classes, packages, operations,
slots are named using symbols so that the lookup of these features by name is
as efficient as possible. If strings were used the lookup would necessarily
involve a character by character comparison. Using symbols the lookup can use
the symbols identity as the comparison operator. You can reference a symbol
by constructing an instance: Symbol(name).
