99 Prolog Problems (http://www.ic.unicamp.br/~meidanis/courses/mc336/2009s2/prolog/problemas/) as solved and explained by Daniel Dušek

	% #1
	% Get last element from the list
	% Explanation:
	% Last element of list containing one element is the element
	% Recursively call my_last on TAIL of the list, in rule head notice the underscore
	% sign. We put it there because our rule body does not need to contain named
	% reference to the list head - in other words, we don't care about it.
	my_last(X, [X]).
	my_last(X, [_\|T]) :- my_last(X, T).
