# Values are _not_ objects. Specifically they have the following properties not found in objects:
|
|
# - they are immutable
|
|
# - equality implies identity == is ===
|
|
# - they have type, not class
|
|
|
|
# To make them useful in an oo system, we assign a class to each value type
|
|
# This makes them look more like objects, but they are not.
|
|
|
|
# Value is an abstract class that unifies the "has a type" concept
|
|
# Types are not "objectified", but are represented as symbol constants
