require_relative "indexed"
# A List, or rather an ordered list, is just that, a list of items.

# For a programmer this may be a little strange as this new start goes with trying to break old
# bad habits. A List would be an array in some languages, but list is a better name, closer to
# common language.
# Another habit is to start a list from 0. This is "just" programmers lazyness, as it goes
# with the standard c implementation. But it bends the mind, and in oo we aim not to.
# If you have a list of three items, you they will be first, second and third, ie 1,2,3
#
# For the implementation we use Objects memory which is index addressable
# But, objects are also lists where indexes start with 1, except 1 is taken for the Layout
# so all incoming/outgoing indexes have to be shifted one up/down
