You can expand the template arguments into an array by putting it 
into square brackets: [args]. You can format an array with the 
default notation using %s, for a custom format you can use %( and 
%). See https://dlang.org/phobos/std_format.html

```
void main() {
	foo(1, 2, 3);
}

void foo(T...)(T args) {
     writefln("%s", [args]); // prints [1, 2, 3]
     writefln("%(%s; %)", [args]); //custom ; separator, prints 1; 
2; 3
}
```
