lsh 2.1 (new formula)

New formula for lsh.
Yep, exactly like that! I find it looks cleaner than other arrays when you will only have strings as members, since you can omit the quotation marks and commas that are required for regular arrays.

(Stylistically we'd prefer

```ruby
args = %W[
  --example
  --example2
]
```

But it's not a huge deal.)
