- list append - append a list to another

- list split - first n elements to first outlet, rest to second outlet
- list trim - trim off "list" selector
- list length - output number of items in list
- list nth - nth item in list, counting from zero

-Not sure we need these:
- list cat - build a list by accumulating elements
- list foreach - spit out elements of a list one by one
- list array - get items from a named array as a list
- list reverse - permute elements of a list back to front
- list pack - synonym for 'pack'
- list unpack - synonym for 'unpack'
- list first - output first n elements.
- list last - output last n elements
