As others have said, rename the .d file, since files are
considered modules. I have since changed my notes to reflect
this change. Sorry for the confusion.

When coming to a new language I tend to write lots of little
snippets (or copy/save examples), and then I name those snippet
files according to the thing being 'snipped'. But, if you do that
in D (and many will do that), and you don't have some module
namespace in your snippets, you'll run it the same trouble I did.
I spent a day debugging because of this ;-)
So, can I suggest that all code samples, by default, have: module
test; (or something at the top).
I'd also recommend making this issue of module namespace, one of
the *first* things people learn, when coming to D, especially
that fact, that the compiler will create a namespace for you (if
you don't) based on the file name.
So if you're writing a book, perhaps that should be in your mind
too ;-)
btw. As I've mentioned on other posts, the current version of GDC
(as opposed to DMD and LDC) will compile such code without issue
(i.e when you don't give a module name), and it will correctly
work out the correct namespace to use(apparently a bug - but a
nice bug ;-)
