Good question. My idea is that the "Ports" list would be mutable. And it
would be usable both like a list and a mapping. Here's an API that Gisle
and I just discussed:

Positions are all zero-based.

integer propety length
getItem(string Name) # return None if not there
getItem(integer position) # use language semantics of throwing exception
or return special value
insertItem(Node, [position]) 
  # if a node with the same name is already there, replace it at the
same position
  # elseif position is missing do an append
  # elseif position = length, append node
  # elseif position < length do an insertion in front of the element
with the given position
  # else die
deleteItem(string Name)  # use language semantics to throw exception or
ignore bad names
deleteItem(integer position) # ditto
