Prevent including pluggable.php by plugins

[lilyfan]

It is a bad manner to include wp-includes/pluggable.php by plugins.

Some plugins (such as ​Events Calendar) DOES the implementation, and cause confliction with other plugins which overloads the functions in pluggable.php

To prevent this implementation, insert some code to check the valid timing to load pluggable.php.

At line 478 of wp-settings.php

if ( defined('WP_PLUGGABLE_READY') ) {
  die ( __('A bad plugin attempted premature load of pluggable.php') );
}
define ('WP_PLUGGABLE_READY', true);
require (ABSPATH . WPINC . '/pluggable.php');

At top of wp-includes/pluggable.php

<?php
if ( !defined('WP_PLUGGABLE_READY') ) {
  die ( __('A bad plugin attempted premature load of pluggable.php') );
}

That plugin should change its behaviour, There is NO reason why it should have to do that, All plugin code needs to be run on, or after, the plugins_loaded hook fires.

Invalid due to bad plugin behavior, Closing as wontfix, since checking for things like that adds extra overhead which really isnt needed.. esp. not when the plugin author should be fixing it instead.
