Ah yes.
You're completely correct if you subscribe to Adam's and ketmar's file 
sizes expectation.

A D module and package is one level of abstraction. If that level of 
abstraction starts to fill up and gets large, you split it up.

My rule is soft 1k LOC and hard 2-3k (after that it needs a VERY good 
reason to stay together).

This makes each file to be very right down to the point and do nothing else.

You should be doing this no matter the language IMO. Just the difference 
is in Java only one class is publicly accessible per file. Nothing stops 
you from doing that here either.
