title: Overriding comparison operators in Groovy
body: <p>I would like to override >= operator in Groovy, have found <a href="http://groovy.codehaus.org/Operator+Overloading" rel="nofollow">this</a> page, but I am still not sure how to do it. I have a class Banknote with properties serial and amount and I wish to implement comparison bases on the amount property.</p>
