É difícil falar de Ruby sem mencionar seu framework web mais famoso, Ruby on Rails. Mas não adianta muito encarar o framework sem um prévio estudo da linguagem (o que de fato já observei acontecer inúmeras vezes). Esse post tem como intuito auxiliar na aprendizagem tanto da linguagem como do framework, para evitar que erros comuns como esse tornem a utilização de ambos um desastre.

Ruby

Ruby é uma linguagem de programação que apareceu para o mundo em 1995, criada por Yukihiro "Matz" Matsumoto. Tem como características o fato de ser uma linguagem de uso geral, com tipagem dinâmica e forte, orientada a objetos e que incorpora diversos paradigmas de programação, como o funcional e o imperativo.

Two Simple Changes to Simplify class

I'm not suggesting drastic action. I don't want to break backwards compatibility. I simply want to make the class feature more usable to a broader cross section of the community. I believe there is some low-hanging fruit that can be harvested to that end.

Imagine AutoMaker contained class Car, but the author wants to take advantage of prototypes to enable factory polymorphism in order to dynamically swap out implementation.

Stampit does something similar to this in order to supply information needed to inherit from composable factory functions, known as stamps.

This isn't the only way to achieve this, but it is a convenient way which is compatible with .call(), .apply(), and .bind().
