Subscript adverbs 🆕
When you subscript an array or a hash — @a[2],
%h<key> — you can attach an adverb to change
what the subscript does. Instead of just fetching the value, you can ask
whether a key exists, delete it, or get the key and the value
together.
These adverbs are written after the subscript with a colon, and they work the same way on both arrays and hashes. This section covers the most useful ones.
