When someone who writes that style of code (in C++, no less!) &lt;i&gt;knows&lt;/i&gt; that one of the intermediate values could be null, so they use a set of macros involving setjmp and longjmp, and trap SIGFPE, all to implement a fragile sort of try/catch for null de-references.&lt;p&gt;Clever? Insane? Horribly un-portable and prone to breakage depending on compiler, libc, and OS versions? All of the above!&lt;p&gt;(And yes, I have seen this coding style used in multiple projects at a major corporation. It was a favorite of a coder-turned manager, which means it tended to sneak in on any project he supervised.)</text><parent_chain><item><author>pohl</author><text>I&apos;d like to have a dollar for every time I&apos;ve seen a NullPointerException on some line that was constructed by someone who loves the list of methods that automagically pops up for the dot operator:&lt;p&gt;&lt;pre&gt;&lt;code&gt;  foo.bar().baz().qux()
