Variable
Mutable value
Definition
Mechanism
A named container whose contents can change while the name continues to refer to the same thing. A dimension of freedom in the problem space: what varies is the contents, not the identity.
Invariants
- The name denotes the same variable before and after its contents change.
- A reported value carries when it was read.
Risks
Failure modes
Stale read treated as current, so a clock difference is attributed to the parties.
Identity reused
one name rebound to something that is not a later state of the same quantity.
Relationships
Root pattern: builds on nothing in this library.
