closures questions

Hi, I am sending this on behalf of Kalle: 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. 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')); 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 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. regards, Lukas Kahwe Smith mls@pooteeweet.org
