Assuming hours, minutes and seconds are already declared, you can do this already

TypeTuple!(hours, minutes, seconds) = dur.parts;

A full working example of the syntax:


import std.typetuple;
import std.typecons;
import std.stdio;

void main()
{
        int a,b;
        TypeTuple!(a, b) = tuple(5, 8);
        assert(a == 5 && b == 8);
}

*Assuming they're already declared* is the thing to note. There's little point in a tuple destructuring syntax if you have to declare the variables beforehand anyway.

I would say it's still quite useful, but I agree it's not ideal.
