Comment:

 This is still a valid ticket as of WordPress 5.2. If this function is used
 within the setup_theme hook or earlier, the warning will be thrown.


 {{{
 Warning: Use of undefined constant TEMPLATEPATH - assumed 'TEMPLATEPATH'
 (this will throw an Error in a future version of PHP) in
 wp-includes\theme.php on line 152
 }}}
