 The __() function is used in multiple frameworks and other open source
 libraries.

 When both systems (e.g. WordPress and Laravel or WordPress and Magento)
 are required in one composer project the 'function already exists'
 Exception got thrown.

 To override the function behaviour and/or be compatible with other
 frameworks like Laravel the functions should be wrapped within a
 'function_exists' condition like so:

 {{{#!php
 <?php
 if (! function_exists('__')) {
     function __( $text, $domain = 'default' ) {
         return translate( $text, $domain );
     }
 }
 }}}


 Especially the Laravel core does the same:
