You have nothing to be sorry of, good Walter, you are not supposed to read every silly thing that I post on this newsgroups.
I like Design by Contract (DbC), even if I don't use it often. I think DbC is a very requested feature for Java because Java programmers already have good ways to perform unit testing. I think unit testing is more important & useful than DbC (even if their purpose is not the same). And I think current D built-in unit test system is handy and easy to use, but not good enough. Time ago I have listed few basic missing features. One of the most important ones is to be able to see the number and names of the unit tests that have failed. And D being so good at compile-time processing will need some way to do compile-time unit testing too, for example with a way to catch and summarize compile-time asserts, listing how many of them have failed.
I don't use DbC often, but I use unit tests a *lot* in D, I use them in every function and class I write in "production" code. In D I write 1-2 lines of unit tests for every line of code. I also use coverage analysis often (well, I'd like to use it, but LDC doesn't have this feature yet, and the coverage analysis of DMD is partially broken, especially for largish programs), and profiling (kinda missing in LDC).
Bye,
