Ruby constant lookup

gistfile1.txt

Document = 'hello'

class Question
end

class Animal
  puts Question::Document
end

class Question
  class Document
  end
end

--output:--
1.rb:7: warning: toplevel constant Document referenced by Question::Document
hello
It looks like ruby searches enclosing scopes for a constant when it isn't found in the specified scope. I think the warning is a penalty for being unable to think up more than two variable names.


Note: If top level constant is required/defined first, it will be used instead of namespaced one
