1) Closures on class properties just don't work, the only way to do it is
to do something like:

$c = $a->b;
$c();

Calling: $a->b(); will result in method A::B() does not exists.

would be nice to get this fixed, but at worst it should be documented.

2) Closures can be defined as constants values because of its toString method:

define('Closure', function(){ echo 'Test'; });

echo constant('Closure'); /* (string) Closure object */

3) Since Closures have this toString method, but its not showing up in Reflection:

Reflection::export(new ReflectionClass('Closure'));

so do we even want the toString() method?

4) var_export() and Closures is useless, any call to var_export() like the example
below will all be the same:

$lambda = function()
{
   echo 'Λ Lambda';
};

var_export($lambda);

/*
Closure::__set_state(array(
))
*/

Maybe it could return some relevant information for exporting the closure across
data

not a huge biggy to me.

5) Its impossible to clone a closure using the cloning keyword:

$a = function(){};
$b = clone $a;

This makes it hard to make a copy of the closure because of objects always are
passed by reference.


I guess this is a draw back from the OO approach (rather than the original resource approach), but solvable?
