Hi all,
I'm Merlin, I'm just starting out in D and super excited.
My questions are:-
1. In a range pipeline how does one handle the event of a
filter range returning empty?
2. How does one unwrap a single result from a range operation?
Look forward to your assistance!

1. you don't have to handle it.
it just won't go.
2. `takeOne` put it into the search on the dlang site
Thanks for the quick response!
Took a look at takeOne and yep that's the ticket.
What I meant about the handling an empty filter is, what if I
want to take an alternative route if the filter returns empty?
You check if it's by calling empty.
or do you want a default value? I am sure there is a convince
function for that somewhere in phobos.
