Using pattern matching you can easily operate with complex data structures in most expressive and eloquent way. Elixir provides pattern matching like any other functional programming language.

In this case you may take a look at Highland.

Ruby is a great example of multi-paradigm programming language: it allows you to write code in object-oriented, imperative or functional styles. Ruby have much in common with functional programming languages: high-order functions, closures, anonymous functions, continuations, statements all values. If you want to use more functional programming patterns and tools, you might want to take a look on Functional Ruby gem.
