Actually, I think this feature is somewhat missing in U++ (and is quite common in other frameworks).

But I am quite sceptical about those cast overloads too.

Imo, something as simple as

template<class T1, class T2>
struct Pair {
Pair(const T1 & _t1, const T2 & _t2) : t1(_t1), t2(_t2) {}
Pair() {}

T1 first;
T2 second;
};

would solve most of usage scenarios where I was eventually missing tuples.

Maybe first/second are bad names though...

Hm, maybe, what about

template<class T1, class T2>
struct AB {
AB(const T1 & _t1, const T2 & _t2) : t1(_t1), t2(_t2) {}
AB() {}

T1 a;
T2 b;
};

? Smile

Here is boost's take on the issue:

http://www.boost.org/doc/libs/1_34_0/libs/tuple/doc/tuple_us ers_guide.html

IMO a little bit overengineered...
