The attached files compile but do not link. There is an undefined reference
to the template constructor.
If I copy it into one file it works...

Works for me:
dmd modules.d token.d

Probably you're forgetting to put "token.d". Don't, so it'll get linked.
Another option:
dmd -c modules token
link modules.obj token.obj

Do you use Windows? Then this might be a linux only bug. I'm pretty sure that the file is linked in.

I looked at the files using nm.
nm showed that the undefined references are local symbols instead of global
ones.

Template instances are still not handled correctly on Linux.
The compiler generates lokal symbols for template instances. This is the reason why you can't link it.
