It's important to keep them separate regardless. static foreach is close 
to useless if it introduces a new scope for its body.

I.e.:

int main(){
     foreach(_;Seq!int){
         int x;
     }
     return x; // error
}

int main(){
     static foreach(_;Seq!int){
         int x;
     }
     return x; // ok
}
