Hello,

i just wondered where the difference between the following code parts is?

  ---- code ----

class << Array
  p self.inspect
  define_method :foo do
    p "inside foo"
  end
end

Array.class.module_eval do
  p self.inspect
  define_method :bar do
    p "inside bar"
  end
end

Array.foo
Array.bar

  ---- output ----

"#<Class:Array>"
"Class"
"inside foo"
"inside bar"
 =20
  ---- end ----


it obviously makes a difference because self.inspect returns two different =
values. but how is this practically relevant?

Greetings,
Niklas
