The typing errors that would not be found until runtime.

That's actually where TDD shines - since "run time" is
about 10 seconds after writing the code, the number
of type errors that creap through is going to be somewhere
between none and very few.

At least, that's the case if you're using TDD religiously.
(I couldn't resist the pun, and I'm not at all sorry. [grin])
