simple_attrs_benchmark

There are many gems that aim to simplify attribute definition for plain old Ruby objects. Many include rich features such as type checking, coercion and default values. The goal of SimpleAttrs is to provide a bare bones DSL to define attributes and add support for:

1. Mass assignment through the object initializer
2. Provide a reader/writter for every attribute defined

Execute

0. Clone repo
1. $ bundle install
2. $ bundle exec ruby ./benchmark_samples.rb
