If expr represents a tuple, we (Andrei and I) were thinking about the syntax:
auto (a, b, c, d) = expr;
being equivalent to:
auto t = expr; auto a = t[0]; auto b = t[1]; auto c = t[2 .. $];
You can also do this with arrays, such that:
float[3] xyz;
auto (x, y, z) = xyz;
The Lithpers among you will notice that this essentially provides a handy
car,cdr shortcut for tuples and arrays:
auto (car, cdr) = expr;
