Constants defined within a class or module may be accessed unadorned
anywhere within the class or module.
Outside the class or module, they may be accessed using the scope
operator, ``::'' prefixed by an expression that returns the appropriate
class or module object. Like:
class Const
def getConst
CONST
end
CONST = OUTER_CONST + 1
end
Const.new.getConst » 100
Const::CONST » 100
