Subject: Re: Removing a class for good from ObjectSpace

When I simply remove the class using remove_const it will still be
available via the ObjectSpace though, so that doesn't really work :/


Basically I want this test to pass:

class Foo
end

# removing the class somehow

ObjectSpace.each_object(Class) do |klass|
    assert !(Foo > klass)
end
