Constant Lookup Confusion

Ruby
1

Trying to dynamically set a constant, but I seem to either be defining
it in
the wrong place, or looking for it in the wrong place.

module ClassMaker
def self.make_class( classname , default )
theclass = Class.new do
extend ClassMethods
const_set :DEFAULT , default
end
Object.const_set classname , theclass
end

module ClassMethods
def reset
@value = DEFAULT
end
end
end

ClassMaker.make_class ‘MyClass’ , :my_default

begin
MyClass.reset
rescue => e
e # => #<NameError: uninitialized constant
ClassMaker::ClassMethods::DEFAULT>
end

Try self::DEFAULT in #reset, that seems to do the trick.
