pirate = Object.new
def pirate.speak
“Yarrrr”

#=> true

In my last post I explained how the code above forces the interpreter to assign a newly created Singleton class to the […]

There’s no shortage of literature on singleton classes, but it’s rare to see an explanation that covers implementation. This is unfortunate, as the implementation is not complex and familiarity with it leads to a more nuanced understanding.
A good way to look at singleton classes is to ask the question, “What is it that Ruby […]

A good understanding of method dispatch can help in deciphering some of the odder corners of the Ruby object model. Luckily, method dispatch is not only straight forward, but entirely consistent for “normal” methods, singleton methods, and module methods.
In Matz’s Ruby Interpreter (MRI), method bodies are stored in a struct devoted to representing […]
