      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

      list trim - trim off "list" selector
      list length - output number of items in list
! Need to think more about:
!     list foreach - spit out elements of a list one by one (also in reverse?)
      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 cat - build a list by accumulating elements
+ 
+ Probably don't need:
      list first - output first n elements.
      list last - output last n elements
+     list nth - nth item in list, counting from zero
