As Stuart already said, you can't redefine special forms, and I'm not
sure if dynamically redefining macros makes sense either, since
they're expanded at compile-time—changing them at runtime would be too
late. Furthermore, as far as I know, you can't even do it directly,
because you can't take the value of a macro to use in a binding form.
Binding *functions* like apply of course works normally using the
'binding macro, and *technically* you can change the underlying
function of a macro too, but... I can't imagine a situation where
you'd want that.
