Is it just me, or does that code not compile? I get:
```
Error: type Tuple!(int, "num", string, "name", bool) has no value
```

Adding a paren, with either no args, or full args, fixes it though:
```D
    //auto t0 = Tuple!(int, "num", string, "name", bool)();               //FAILS
    auto t1 = Tuple!(int, "num", string, "name", bool)();                 //OK
    //auto t2 = Tuple!(int, "num", string, "name", bool)(5);              //FAILS
    auto t3 = Tuple!(int, "num", string, "name", bool)(5, "hello", true); //OK
```
