Generate ruby classes from text files.
data = File.read('classes.txt')
classes = data.split(/^$\n/)
classes.each do |klass|
name, *methods = klass.split(/:?\n/)
Object.const_set(name, Class.new do
methods.each do |method|
parse = method.match(/(?<name>\w+) \(?(?<arguments>[\w\, ]*)\)? ?-> {(?<body>.*)}/)
if parse[:arguments].empty?
define_method(parse[:name]) { eval parse[:body] }

Dynamically alias methods and add functionality onto the end of them. Great for creating methods in rails that call `save!`.
