Now I am utterly confused. Can anyone explain THIS behaviour :

### File : foo.rb ###
def requiredfoo
  "I'm here!"
end
#####################

irb> require 'foo.rb'
irb> respond_to? 'requiredfoo'
=> false

irb> def foo ; "I'm here!" ; end
irb> respond_to? 'foo'
=> true

That doesn't make sense at all, right?
