uhm... autoload is not called!

another suggest:
Closure is a special class\type

so it must be global
in a namespace i have to use

public function method(\Closure $x){}

instead of

public function method(Closure $x){}

is it correct? Closure is a special type and final too
 [2008-12-30 17:19 UTC] info at netmosfera dot it 
ok, with __autoload in global namespace works

if you remove the closure but works too

where's the problem?

hi, thanks for accepting this bug

i have one request, is possible to make autoloads for namespaces?
is this back compatible?

namespace a
{
      function __autoload(){echo "a";}
      new Pippo();
}


namespace b
{
      function __autoload(){echo "b";}
      new Pippo();
}

thank you

I think you can easily implement it in user-space by using either one autoloader checking class name or using multiple autoloaders and http://www.php.net/manual/en/function.spl-autoload-register.php

I'm not sure it is practical to do it in the engine as it would require a lot of search around for autoloaders by the engine. I think it's better done in user-space.

The initial code reported as a bug works, and the request for namespaced autoloaders is possible in userland code with no new core functionality needed.

If there is still an issue, please cam you clarify what it is?
