Re: Error with lists

[Norberto Eiji Nawa]

Hi David,

I guess you can think of list/heatList as the head of the list, a
special structure on which one can add member nodes (e.g. using
addLast). 

This explanation is most clear if you check the documentation of
removeAll; the only difference between removeAll and deleteAll is that
the latter will also drop the members nodes. The head of the list is
left untouched in both cases, leaving open the possibility of adding
new members. In the referred example, [list drop] could be performed
after [list deleteAll].
