           Summary: tuple.length rejected as a tuple parameter in a static
                    foreach
           Product: D

        OS/Version: Windows
            Status: NEW

          Severity: normal

This bug was created from Bug 2687.
Workaround (D2), change the foreach to enum args_length = args.length; foreach(
x ; Range!(args_length) ){ }

---

template Tuple(T...){
    alias T Tuple;
}
template Range(int b){
        alias Tuple!(1) Range;
}
void foo()(){
     Tuple!(int, int) args;
     foreach( x ; Range!(args.length) ){ }
}

void main(){
    foo!()();
}
