Description:
------------
The online manual clearly states that require_once
(and related actions such as include) are *statements*.
There is no documented return value.
It also states that "if" is a *statement*.

But actual code sample (from a running
system) shows that require_once
(and related actions such as include) can
be used like a function (see attached code),
and even odder, the "@" operator can suppress
errors.

Now, you can't do that with "if" statement.
So, if require_once is a statement, you shouldn't
be able to do that.  If it is a function,
it should be documented as such.

So, is the following code wrong?

Reproduce code:
---------------
<?php
 
if (! require_once /* require_once as a function */(APP_ROOT_DIR.'EcWebFramework/conf/Includes.php')) {
            $msg = 'Can not load Includes - check filesystem.';
            error_log($msg);
            die($msg);
}

@include_once( $includePath ) ; /* @ supressess error */

if( !@include_once( $include_file ) ) / *both wierdnesses */
{
            $this->__errorAlert( 'TemplatePower Error: Couldn\'t include script [ '. $include_file .' ]!' );
            exit();
}

Expected result:
----------------
I expected to get a complaint about illegal syntax.

Actual result:
--------------
Above code runs without complaint.
