Trying to write a haskel

Listhp.rb

class AnLisp
  def self.method_missing(name, *args, &b)
    if name =~ /(.*)=$/
      define_method(name.to_s.gsub('=', ''), *args, &b)
    else
      super if defined? super
    end
  end
end

Jimmy = Class.new(AnLisp) do
  self.name = ->(a) { puts "I am #{a}" }
end

Jimmy.new.name("Jim")

# Don't suppose you know of a way to avoid the need for the "self." in self.name?
# Can one define another #method_missing on Jimmy instances?
