Addressing the last element of a list

[pinkfloydhomer at gmail.com]

Or alternatively:

Is there a way to make reference to the last element of a list, to use
as a shorthand:

ref := &lst[len(lst) - 1] # I know syntax is wrong, but you get the
idea

and then using the last element of the list by (assuming the element is
a dict):

ref["foo"] = 42
ref["bar"] = "Ni!"

etc.
