<p>This macro functions accepts the same syntax as <code>format!</code>. The prompt is written to
|
||
<code>stderr</code>. A space is also printed at the end for nice spacing between the prompt and
|
||
the user input. Any input starting with <code>'y'</code> or <code>'Y'</code> is interpreted as <code>yes</code>.</p>
