It is quite normal to consider lists and arrays to be different things.
In Perl for instance you can use list operations like `grep` on arrays,
but you cannot use array operations like `push` on lists. For JavaScript
programmers it actually seems common to confuse the two, like with
var node_list = document.getElementsByTagName('example');
for (var ix = 0; ix < node_list.length; ++ix)
node_list[ix].parentNode.removeChild(node_list[ix]);
which would remove all the children if node_list was an array like any
other. Pretending node lists are arrays in nomenclature would likely add
to that.
