[s5; One aspect that makes development in Ultimate`+`+ very orthogonal
is the existence of Value `- the polymorphic value type. Any
of Ultimate`+`+ basic types (int, double, String, Color, Rect,
Font, Image etc...) can be stored into and retrieved from a Value.
Value itself can be queried for the type of value it contains.
It is also very easy to make any custom types Value`-compatible.&]
[s5; Related to Value is the general concept of `"empty value`".
The Ultimate`+`+ special constant Null represents an empty value.
Most concrete types support Null. Null is also defined for fundamental
types `- int, double and int64 `- as a value that is lower than
any other value for specific type (for example, Null is equal
to INT`_MIN for int). To test whether a variable of a certain
type is Null, you can use the generic IsNull function.&]
