Why does (SETF (LDB 0303 X) 5) wrap a lambda around things, binding
the internal variable to 5 ?
So it can return the correct value. There is no smarts about the value
to be stored being repeatable. The slight improvement in code is not worth it,
since it only shows up when you use it for value (in the compiler).
