I use modules for grouping compile time configuration options in 
independent files that can be swapped out. The module name 
doesn't match the file name because there are several files with 
the same module name, only one of which is used at a time.

It is also valuable to swap out library implementations. For 
example, when modifying Phobos modules, instead of recompiling 
the whole thing, I can just specify the path to my modified 
version.

dmd yourfile.d phobosfork.d

no need to recreate layers of folders just to appease a random 
rule.

I also hate having empty folders laying around, and matching 
names would force that.
