Class: PatternMatching::Bindings

Inherits:
BasicObject
Defined in:
lib/pattern_matching/bindings.rb

Overview

Taken nearly verbatim from the idea presented by Avdi Grimm in an episode of the fantastic Ruby Tapas series, including the use of the >> (right-shift) operator as a “guard” operator, as visually stands out compared to other define-able binary operators but it lacks idiomatic re-use the way that << (left-shift) does. It also feels a little bit like the \ guards used in Elixir, which I would have used, if I could find a way to have Ruby treat either \ or // as a binary operator.
