So as you showed it's not as bad as I thought, which is good, however my point
was that in my scenario, which I argue is indeed very common, it could be
implemented as a "nested anonymous function". My reasons:
1) Nested functions already exist and merely need an anonymous parser to be
implemented (as I already did in that branch).
2) The interface is literally 100% useless as the object is never passed
outside of the receiver (SortEntities). It will be created and destroyed with
absolutely no value to the program whatsoever.
