Reply to Daniel,
Well of course it can't compile: YOU MOVED test.d! What do you expect
when you tell it to import a file that no longer exists? The compiler
is not psychic.
If you really, absolutely have to have the two parts in different
directories, just generate a header file.
dmd -H -c -o- test.d
That generates test.di, which you have to make available to prog.d.
Of course, in this particular case, test.di is exactly the same as
test.d, since all the functions are small enough to be inlined.
ditto. I was going to post exactly that point.
