Subject: Why doesn't method_missing affect respond_to?

Take this class:

class Foo
  def method_missing(m, *args)
    m.to_s
  end
end

irb(main):006:0> Foo.new.foo
=> "foo"
irb(main):007:0> Foo.respond_to? :foo
=> false

This obviously just returns the name of any method that doesn't exist
for the object.  So if you can send the object any message and get a
result, why doesn't it respond_to those messages?
