The difference between this command and <code>eval-minibuffer</code> is that here the initial <var>form</var> is not optional and it is treated as a Lisp object to be converted to printed representation rather than as a string of text. It is printed with <code>prin1</code>, so if it is a string, double-quote characters (‘<samp>"</samp>’) appear in the initial text.
