It will call foo.func, because the module foo is in scope in module prog 
and hence hides the namespace foo in module bar.

You can already try this today, as the DIP _does not actually introduce 
any new lookup rules_:

module a;
void func(){}
//---
module bar;

mixin template X(){
     void func();
}
mixin X foo;
//---
import foo,bar;

void main(){
     foo.func();
}

In particular, any problems you find with symbol lookup are actually 
orthogonal to the DIP.
