Hi Stas, hi everbody,

I think the issue is, that PHP does not have defined properties with
attached validation (yes, I know about __get()/__set()). Now we just
have plain properties that may contain everything. If we would have
something like this:

class Clazz
{
   public $property
   {
       function get()
       {
           return $this->property;
       }
       function set($property)
       {
           $this->property =3D (int)$property;
       }
   }
}

In this case it, maybe it would make sense to allow definitions of
properties in interfaces. For example the following could require a
property to be read only:

class Clazz
{
    public $property
    {
        function get();
    }
}

An interface defines a halfway strict API. Allowing the current
properties in interfaces would not add any sensible functionality
because it would not define the API better.

cu, Lars
