TDD strikes me as an ad-hoc way of constructing code, and is a poor substitute 
for thinking about the problem as a whole. For example, I don't really see how 
getting a square root function to pass its test cases is going to lead one to 
implementing one of the classic algorithms for computing square roots. I don't 
see how TDD for a compiler will lead one to rediscover what is known about the 
best way to organize the logic of a compiler.

TDD is "curve fitting" which is what one does when one has no understanding.

D's support of unit testing is not an endorsement of TDD.
