Thanks for bringing the topic up.

I would much rather go with the second solution, that is, move 
the files from `src/` to `src/ddmd/`.

That will prevent some silly conflicts you can see with 
un-packaged modules. One bug we witnessed during the D2 porting 
is for example that any module which has the same name as one of 
it's symbol (in our case, `Version.Version`) is unusable if the 
module is imported unqualified, because the module itself is a 
symbol.
