I like the concept of extern functions in this concept, though it does rise
questions of what scopes/modules are used for match searching. However, the use
of Foo to mean the class name seems like the wrong keyword. What if I truly
wanted a function that took a Foo? Also, it makes these function definitions
behave differently than definitions outside the interface. Perhaps 'super' or
'typeof(this)'?
