Very peculiar behaviour with wire('pages');

[joe_g]

So I ran into this peculiarity: If I put this piece of code at the end of my 'util.php' (included first on my head.php) — then things work:

<?
    function totallyRandomFunctionName() {
        /* wire('pages');*/
    }
?>

Note how wire('pages') is commented out, but it still somehow does the job.

Now, if I remove the commented line:
 

<?
    function totallyRandomFunctionName() {
        
    }
?>

Then I get this error earlier in util.php, suddenly the wire function isn't existing...:
Uncaught Error: Call to undefined function wire() in /xx/util.php:86

Line 86 has: "wire('config')->urls->root" in it.

I'm quite curious what goes on here!

I assume you are using the namespace in your util.php file?

<?php namespace ProcessWire;
