D does not support C++ semantics. You cannot split namespaces into

For namespace NS, all the declarations in NS have to be in one file and

It's about namespace overloading.
The following works, even though no scopes are actually extended with 
new symbols.

module other;
template foo(){ // a scope
    void foo(){}
}
// ----
import other;
alias foo=other.foo;
template foo(){ // another scope
    void foo(int){}
}
void main(){
    foo(); // successful
    foo(2); // ditto
}
