All I really mean is that Proxy.Handler should be an object suitable for 
use as a handler prototype. Rather than calling it Proxy.Handler, maybe 
Proxy.DerivedTraps would be better. Then, using Allen's proposed <| 
operator you could do:

p = Proxy.create(Proxy.DerivedTraps <| {
    // fundamental traps, and optionally some derived traps defined here
                            });
