Though sugar seems to be somewhat looked down upon I thought I'd suggest this- having seen the cartesianProduct function from std.algorithm in another thread I thought it would be an excellent piece of sugar in the language. It's not an earth shattering change but it makes something very common more elegant and reduces indentation significantly for multiple nested loops. Braces make nested loops very messy and any significant quantity of code in the loop body benefits from not being in a messy nesting.

What would you do with associative arrays?

void main() {
    auto aa = [1:1, 2:2];
    foreach (a, b ; aa, 1..10)
        foo(a, b);
}
