I see your point. From my point of view, this is simply another case of 
symbols conflicting, similar to symbols with the same name imported from 
different modules. When that happens, the compiler reports the problem, 
and I have to resolve it. Couldn't the compiler look for name.foo.bar in 
both name.d and name\foo.d, and report an ambiguity if one exists? For 
example:

dmd main.d name.d name\foo.d
main.d(6): Error: name.foo.bar has multiple definitions: foo.bar in 
name.d(4), and bar in name\foo.d(2)

----- name.d -----
struct F {
   int bar = 1;
}
F foo;

----- name\foo.d -----

int bar = 2;

----- main.d -----

import name;
import name.foo;

void main() {
   printf(name.foo.bar);
}
