{{omit from|Rust}}
Demonstrate how to dynamically add variables to an object (a class instance) at runtime.
This is useful when the methods/variables of an instance are based on a data file that isn't available until runtime. Hal Fulton gives an example of creating an OO CSV parser at [http://www.devsource.com/article2/0,1759,1928562,00.asp An Exercise in Metaprogramming with Ruby]. This is referred to as "monkeypatching" by Pythonistas and some others.
