Not with arrays, they must be contiguous. But you can use ranges 
instead:

-----
import std.stdio;
import std.range;

void main()
{
     auto orig = [1,2,3,4,5,6,7];
     auto sliceEven = orig.stride(2);
     auto sliceOdd = orig.drop(1).stride(2);

     writeln(sliceEven);
     writeln(sliceOdd);
}

You can convert the ranges into arrays by calling .array on them 
(and importing std.array first), but this will cause allocations.
