Like ix, but for Document values with Text indices

>>> ["someKey" := Float 3.0] ^? key "someKey"
Just 3.0

An indexed Traversal into Array elements

>>> Array [String "hey", Float 2.0] ^.. values
["hey", 2.0]

>>> "Array [Float 2.0,Float 3.0,Float 4.0]" & values . _Float *~ 2.0
"[4.0,6.0,8.0]"

An indexed Traversal into Document fields

>>> Array [Doc ["doc1" := Float 3.0], Doc ["doc2" := Bool True]] ^.. values . fields
[ key: 3.0, key2: True ]

A Traversal into Document values

>>> ["key" := Float 3.0, "key2" := Bool True] & members . _Float *~ 2
[ key: 6.0, key2: True ]

Like ix, but for Arrays with Int indexes

>>> "Array [Float 1.0, Float 2.0, Float 3.0]" ^? nth 1
Just 2.0

>>> "Array [Float 1.0, Float 2.0, Float 3.0]" & nth 1 .~ Float 20.0
"[1.0,20.0,3.0]"

A Traversal into Document keys

>>> ["key" := Float 3.0, "key2" := Bool True] & labels %~ Data.Text.toUpper
["KEY": 3.0, "KEY2": True]
