tuples are your friends

[Gor Gyolchanyan]

I wonder why aren't tuples fully supported in D?

string, int, float createTuple()
{
    return "hello", 5, 6.7f;
}

unittest
{
    string s;
    int i;
    float f;

    s, i, f = createTuple();
}

Wouldn't this be a cleaner way of dealing with static-length
heterogeneous collections of variables?
The comma operator would have a single definite meaning: creating a
tuple out of left-hand variable or tuple and right-hand variable.
The existing use of comma wouldn't change:
* All functions will technically take 1 argument only: a variable or a tuple.
* Comma-separated expressions are technically a single tuple expression.
* UFCS will get expanded to include tuples: ("/", "usr",
"bin").buildNormalizedPath;

It's easy to imagine the same thing but with support for tuples
consisting of any symbols, and nut just variables.
