I learned something recently. Our code used to be peppered with this:

<!--more-->

```ruby
result = something.else || []
```

Or variations on the theme:

```ruby
a_string = (something.else || []).join(',')
```

Turns out you can just

```ruby
result = Array(something.else)
a_string = Array(something.else).join(',')
```

Minor convenience, but lovely nonetheless.
