No, because you can obfusc^Wprotect your widgets with a class interface :)

What it ammount to is saying (within maybe your iface constructor):

   widget->callback(function, this);

your interface class can be inside the scope of a function, and your callbacks
can be outside (or "inside", if they are static) of your interface class.

of course, this is all blatantly C++.

He'd pay people $2.46 for every line of elegant GUI code they produced ;)
