# I don't necessarily love CoffeeScript as a template for, but here is an example
# of metaprogramming via a combination of:
# * "this" bound to the currently created class in class definitions
# * class methods inherited
class Foo
this.hasMany = (types) ->
this.prototype[types] = ->
alert "Looking up #{types}"
class Bar extends Foo
this.hasMany "friends"
new Bar().friends()
# Similar example in Ruby
class Foo
def self.has_many(types)
define_method(types) { puts "Looking up #{types}" }
class Bar < Foo
has_many "friends"
