But unless you have a secret solution to the halting problem,
you will be faced with considerable complexity of deciding
which of these conditions can be checked at compile time
(Indeed I think this could make 4.9 look like a picnic).
After all, you are the first to know that what looks simple
at first sight often turns out not to be.
