That may seem contrived, but you may not know of the f(int) overload, especially in combination with templates.&lt;p&gt;NULL, if #define&apos;d as (void *)0, prevents that error.</text><parent_chain><item><author>vog</author><text>&lt;i&gt;&amp;#62; explicit strong nullptr constant; no more NULL macro nonsense&lt;/i&gt;&lt;p&gt;What is the point of this?
