Const Tuples

[bearophile via Digitalmars-d-learn]

They are not the same type:


void main() {
     import std.typecons: Tuple;
     alias T1 = const Tuple!(int, int);
     alias T2 = Tuple!(const int, const int);
     static assert(is(T1 == T2)); // Fails.
}


This type difference causes some troubles when you use tuples.
