/*
* call-seq:
* rng === obj => true or false
* rng.member?(val) => true or false
* rng.include?(val) => true or false
*
* Returns <code>true</code> if <i>obj</i> is an element of
* <i>rng</i>, <code>false</code> otherwise. Conveniently,
* <code>===</code> is the comparison operator used by
* <code>case</code> statements.
*
* case 79
* when 1..50 then print "low\n"
* when 51..75 then print "medium\n"
* when 76..100 then print "high\n"
* end
*
* <em>produces:</em>
*
* high
