In addition to Kevin Conner's answer: block arguments do not support the same semantics as method arguments. You cannot define default arguments or block arguments.

This is only fixed in Ruby 1.9 with the new alternative "stabby lambda" syntax which supports full method argument semantics.

Example:

# Works

styx

module ActiveRecord
  Base.singleton_methods.each do |m|
    Base.class_eval <<-EOS
      class << self
        puts "redefining #{m}"

        define_method "#{m}_with_introspection" do |*args|
          puts "#{m}"
          send(:"#{m}_without_introspection", *args)
        end
