One of the coolest things in Ruby is the splat operator (*). In short, it lets you destructure arrays into variables, for example:
```
a, * = *[123]
puts a.inspect # 123
```
You can simplify this code even further by just dropping the asterisks:
```
a, = [123]
puts a.inspect # 123
```
If you only need the tail of an array, the leading asterisk is mandatory:
```
*, b = [123, 321]
puts b.inspect # 321
```
