Fully agree with this "too much code in a single file" point. I 
am confident that part of the reason of Phobos unittesting being 
very incomplete, is that adding unittests further clutters the 
codebase.
Moving all unittests to the bottom of the file (pulling them out 
of classes too) would resolve this issue in part.
