New Feature in Ruby 3.4.x

The latest Ruby 3.4.x introduces a new shorthand: you can now use it to reference the single block argument automatically.

In Ruby 3.3.x and earlier, we had to write:

```

['Vaaai'].map { |item| "#{item} Corinthians!" }
# => ["Vaaai Corinthians!"]

```

Now, in Ruby 3.4.x, we can simplify it to:

```

['Vaaai'].map { "#{it} Corinthians!" }
# => ["Vaaai Corinthians!"]
```

🖼️ SQL aliases with hashes

The new version brings even more convenient features. For example, you can now define SQL column aliases using hashes directly in the select method.

Before:

```

Comment.select("moderated_at AS moderation_timestamp")

```

After:

```

Comment.select(comments: { moderated_at: :moderation_timestamp })
```
