Ruby Singleton Objects

Here’s another freebie from the deep RubyTapas stacks. This one is about a truth of object modeling that we don’t often talk about: not every object needs to have state. If an object has no state, there’s no need to have more than one of it. And for stateless objects, having a class just to generate a single instance may be superfluous!Director’s commentary: This one first aired as episode .
