I think I'd be happy with a template in std.algorithm.

    // a[] = b[] + c[]
    auto a = parallel!("a = b + c")(a,b,c);

    // foo(array1[], array2[], array3[], array4[])
    parallel!("foo(a,b,c,d)")(array1,array2,array3,array4);

Or some such. I'm sure Andrei could write that. He's a clever guy.
