I think it makes sense to document this.

Based on internet searches it wasn't always the case, but I couldn't find the changelog where it was fixed. Does it not work 100% of the time? Is there some reason it's not officially documented? Test script: --------------- <?php call_user_func(function() { var_dump(__FUNCTION__); }); Actual result: -------------- /path/to/closure-test.php:3:string '{closure}' (length=9) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77148&edit=1
