I agree that returning the the item (using optional, if necessary) is better in this case 
than returning an iterator, when the iterator is only used as a pointer that will not be 
used for traversing in any manner.

Nice idea about wrapping the function (algorithm) first, and then using the range adaptor 
on the outer.
