Absolutely Nithin! I avoided using attr_reader (and related methods) because I wanted to show how these could be implemented, from scratch. Why miss an occasion to demonstrate metaprogramming!

Instead of:
define_method(prop) { instance_variable_get(“@#{prop}”) }

you can also do this:
define_method(prop)
attr_reader prop.to_sym # prop by itself also worked for me
# code snip — setter method
end
