method_missing

[trans]

Sometimes I have broken down files by the method. So #method_missing could be defined to require a file too to see if that picks up the missing method.

[postmodern]

Interesting idea. Although, that sounds like something different than a namespace? You could sort of accomplish this with OpenNamespace, by putting each method in it's own module:

class Foo
  module Bar
    def bar
    end
  end

  include Bar
end
