Hrm... I just downloaded QSA, the Qt Scripting for Applications. It
adds support for receiving signals in JavaScript. Wanna guess how it
works?

function enabledChangedHandler( b )
{
    debug( "state changed to: " + b );
}

function init()
{
    var obj = new MyObject;
    // connect a script function to the signal
    connect( obj, "enabledChanged(bool)", this, "enabledChangedHandler"
);
    obj.enabled = true;
    debug( "obj is enabled: " + obj.enabled );
}

Here's the big question: How do they do it in the C++ code? Same way as
PerlQt. Even they don't bother with a pretty introspective wrapper
class. In fact, ALL of QSA is a big damned invasion of the QMeta*
hierarchy looking for properties, signals and slots. *grumble*
