I usually just use version(unittest){...} at the top of the file to make
module-wide unittest helper functions. I don't like modifying the thing
I'm testing just by the act of testing it (e.g., adding class members
when running unittests for that class). This may be a fact of life in
quantum physics, but for testing code I prefer the "independent
observer" mode of operation. :)
