I didn't know that. Thank you.

In this case, TupleDeclaration syntax is similar to ParameterList.

void f(int i, string j){ ... }
(int i, string j) = tuple(1, "a");
auto (i, j) = tuple(1, "a");

But, 1 parameter function does not allow isolated comma.

void f(int i){ ... }
(int i) = tuple(1);
auto (i) = tuple(1);

//void f(int i,){ ... }  // invalid
//(int i,) = tuple(1);   // associatively invalid
//auto (i,) = tuple(1);  // associatively invalid

How about you?

I didn't know following syntax is valid...

void f(int i, ){  }
(int i,) = tuple(1, "a");  // associatively valid
auto (i,) = tuple(1, "a"); // associatively valid

Hmm, it is hard achnowledgment to me, but it is valid syntax for consistency...
