Symbol
object represents a Ruby name and is generated
automatically using the :name
literal syntax. The same Symbol
object will be created for a given name string for the duration of a
program's execution, regardless of the context or meaning of that
name. Thus if Fred
is a constant in one context, a method in
another, and a class in a third, the Symbol
:Fred
will be
the same object in all three contexts.
