Filter is a template and returns a FilterResult range which is

for map and the majority of functions in std.algorithm.

You can also use .array to (greedily) evaluate the results, which 
(for filter) will return a range of the same type as went in:

void main()
{
    import std.array : array;
    int[] arr = [1, 2, 3, 4, 5];
    int[] result = arr.filter!(x => x%2).array;
}
