Kotlin's function literals have a shortcut for one-argument literals:
the single argument doesn't need to be explicitly named, but can be
referred via the 'it' contextual keyword.
For example, 'array(1, 2, 3).filter { x -> x % 2 == 0 }'
-> 'array(1, 2, 3).filter { it % 2 == 0 }'
Add an intention action for this transformation.
