+automatic leave on failure</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>The case of <codeph>new</codeph> failing is so common that a version of <codeph>operator
+new()</codeph> has been written which takes a single parameter <codeph>ELeave</codeph>,
+indicating that it must leave if it was unable to allocate memory.</p>
+<p>Use <codeph>operator new()</codeph> so that there is no need to check the
+result of the <codeph>new</codeph>.</p>
