One thing I found confusing was the comment for the class_def method

However it actually defines an instance method

require "metaid"

class MyClass
   class_def "class_method" do puts "success" end
end

MyClass.class_method
   #=> undefined method "class_method" for MyClass:Class

MyClass.new.class_method #=> success
