That's an interesting question. I imagine such a tool to be immensely helpful when validating /
debugging software.

In what way to you think a static analysis tool can help ? Synopsis can't guess the domain
of all possible values, and so can't know if all values are tested for. In the same
line of thought I don't think exceptions are an appropriate means.
All synopsis can do is test that the return value is *used* (at least once), and issue a
warning if not. That in itself will already be very useful.
