OK. I still believe that this slight flaw is worth the benefit of def time
checks, but accept your judgement that the use cases I have in mind are not
common enough to justify it. Consider my proposal withdrawn.

Sigh. I think unit tests are great. I write unit tests for all of my code. I
have a script that runs all the unit tests on our development branch
overnight and emails me about the things that fails. I'm not motivated by a
dislike of unit-tests. If anything, I am too much a believer in testing
which is why I advocated the option to have more testing facilities (i.e.,
def time tests). I think having more options available for testing is a good
thing and I don't understand the vehement objections people have to anything
that vaguely resembles static checks.
