Match Operator Guards
2024-04-08
This article discusses an experiment aimed at introducing guard clauses to Elixir's match operator, which traditionally does not support them. Brett Beatty details his approach to extending Elixir's pattern matching capabilities by creating a macro to handle guards in match expressions. His exploration includes dealing with compiler errors, manipulating quoted expressions, and ensuring code clarity in guard implementation. The experiment's goal is to make match failures occur when guards are not satisfied without fundamentally changing match operator's behaviour. The article outlines the challenges, solutions, and considerations for creating a more flexible and expressive matching mechanism in Elixir.
