Subject: trouble understanding const_set()

Hello,

I'm trying to understand why the following code is giving me an error.  It
seems like it isn't finding Foo::Constant (which doesn't exist), but why
isn't it looking for Bar::Constant, instead?

As you can see, `self' is Bar, not Foo:


irb(main):001:0> class Foo
irb(main):002:1>   def Foo.foo
irb(main):003:2>     const_set 'Constant', 'just a string'
irb(main):004:2>     puts self.inspect
irb(main):005:2>     puts Constant
irb(main):006:2>   end
irb(main):007:1> end
nil
irb(main):008:0> class Bar < Foo
irb(main):009:1> end
nil
irb(main):010:0> Bar.foo
Bar
NameError: uninitialized constant Constant at Foo
        from (irb):5:in `foo'
        from (irb):10
irb(main):011:0> Bar::Constant
"just a string"


Any help would be much appreciated,

Chris
