Consider the following equivalent code using zip and lockstep respectively to
iterate over the entries in an array and set their values:
auto arr1 = new double[10];
foreach(i, ref x; zip(iota(10), arr1))
{
x = i;
}
writeln(arr1);
auto arr2 = new double[10];

I think that currently there isn't a simple way to do it. What is
your use case?
