The above does not work (Error 42: Symbol Undefined _D1a3fooFZv). Adding
extern to foo in module b changes nothing. extern( C ) works, but seems
like a hack. Better ideas?

Using extern (C) is the only way I've seen this done.  I don't know of 
any way to make the symbols match up otherwise.  There's probably some 
hack that works, but is uglier than the more straightforward solutions. 
 You could always create a b.di file, if that doesn't defeat the purpose.
