    Well, I tend to agree with your previous decision on this.  Having
Enumerable#include? be an alias for Enumerable#member? (or vice-versa),
but having Range#include? behave differently from Range#member? would be
confusing.  I think it would be better to leave these two methods as
aliases and add a new method to Range for the interval check.  My
leading candidate for this method is now David A. Black's suggestion of
#encompass?.  This is a great name and I really like his idea of
extending it to accept Ranges as parameters so that
(1..10).encompass?(2..9) == true.  Other synonyms could also work:
#enclose?, #surround?, and even #contain?.
