This is mistake I made too, when i began using D.

I quickly got into the habit of putting

module test;

at the beginning of every file I create, unless I determine a 
better module name.

Actually, I wrote my own IDE, so it does that for me whenever I 
select a new D file.

Personally, I think that is one of the first things newcomers 
need to learn about - modules.

"Modules have a one-to-one correspondence with source files. The 
module name is, by default, the file name with the path and 
extension stripped off, and can be set explicitly with the module 
declaration."

"Modules automatically provide a namespace scope for their 
contents."
