"::Foo::Bar::Baz"

Baz.new.say

Foo::Bar::Baz.new.x

This doesn't seem like the expected result. Have I misunderstood how constants work?

[andhapp (Anuj Dutta)]

The call to 'Baz' in method 'x' will look up the ancestor chain and find the Baz constant defined for Object(because of class Baz) and uses it. However, if you qualify the call to Baz like this:

def x
Foo::Bar::Baz.new.say
end

Then it will give the desired result.

But isn't Baz defined at the immediate Foo::Bar scope? Why does it keep going up the chain?

class Foo::Bar::Baz does not open the Foo::Bar scope. class Foo::Bar; class Baz does however.

As Magnus Holm has explained, it's the spec.
