How to build a singleton using intro method:

intro @(Nonempty List) 1 ===> [1]

The easiest way to define it is to use ya-literal package:

items = [1, 2, 3, 4, 5, 6, 7, 8, 9]

You can traverse a Nonempty List but you have to specify in which order you want to do it:

items `yokl` Forth `ha` World `ha` output ===> 123456789
items `yokl` Prior `ha` World `ha` output ===> 987654321
