This came about while trying to construct an ActiveRecord query.

Note that merge combines WHERE clauses using AND. While ActiveRecord does not currently have the ability to combine relations using OR instead, it is coming in ActiveRecord 5 (https://github.com/rails/rails/commit/9e42cf019f2417473e7dcbfcb885709fa2709f89).
It'll look something like this:

One of the many reasons I love working with Ruby is it has a rich vocabulary that allows you to accomplish your goals with a minimal amount of code. If there isn't a method that does exactly what you want, it's usually possible to build an elegant solution yourself.
Let's take the example of simulating the rolling of a die.
We can represent a die as an array of its faces.
die = [*?⚀..?⚅]
# => ["⚀", "⚁", "⚂", "⚃", "⚄", "⚅"]
