class Symbol < Object

A 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.

module One class Fred end $f1 = :Fred end module Two Fred = 1 $f2 = :Fred end def Fred() end $f3 = :Fred $ 2305294 $ 2305294 $ 2305294
