Deprecation error on Alpha-2 that I’m trying to understand… failing

[lloydsargent]

This is the code:

composer/ClassLoader.php

/**
 * Scope isolated include.
 *
 * Prevents access to $this/self from included files.
 */
function includeFile($file)
{
    include $file;
}

Twig calls it and I get the following:

Exception has occurred.
Deprecated: Optional parameter $callable declared before required parameter $arguments is implicitly treated as a required parameter

Not being a PHP expert, I know what the code does, just not what the error actually means or, better yet, how to fix it.

Set error_reporting in your php.ini to a value recommended for production servers, e.g. error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT.

I’m puzzled how this changes the fact that it is deprecated?
