From what I can gather the output of `std.algorithm.iteration :
filter` is a `FilterResult` type.
I need a bit of help dealing with this type:
1. Why this type is there in the first place instead of simply
using the type of input range?
2. Where is the documentation for this type? The documentation
always uses `auto` for `filter` return values.
3. How can I convert this type back into a range?
Thanks.
