To be a little clearer, if the files are all merely reshuffled into various 
packages, then they all violate the rule:

     *** Never import a file from an uplevel directory ***

and understanding is not increased at all. And it isn't even just an uplevel 
directory, it's up then sideways then down.

There *is*, however, documentation on the dmd source files:

   https://dlang.org/phobos/index.html

Click on "dmd" on the left. For anyone wishing to get a tour of the files and 
what they do, this is the place.

Adding better Ddoc comments to the source files will help with this, of course.
