PHP 5.4 introduces the callable typehint to allow closures, string $function and array($obj, 'method'). See for details. HipHop analyzes callable as UnknownClass.

HipHop does not currently support all PHP 5.4 features. We plan to add support for the "callable" typehint some time in the coming months.

This is still failing for me:


function callMe(callable $b) {



callMe(function() {

    echo "hello\n";



HipHop Fatal error: Argument 1 passed to callMe() must be an instance of callable, Closure$callMe$47daeefeedcd4b135f362b25e98454cc$ given in /Users/evert/code/sabre/event/tests/foo3.php on line 7

@paroski, this seems to work only when EnableHipHopSyntax=1. Any idea why?
