Primes¶
- Immutability
- The defining move is to forbid in-place mutation, so that every state a system has ever held remains a distinct, separately referenceable, tamper-evident entity rather than being overwritten and lost.
This sourceFoundational treatment of immutable, persistent data structures: change is realized by constructing a new value that shares unchanged substructure while the original remains addressable, separating the state-holding entity from the act of update and exposing the destroy-vs-retain design choice.
Supported in partVerified against the publisher's abstract
Okasaki's title and abstract establish purely functional (non-mutating) data structures, but no sentence in the held evidence states the claim's persistence or tamper-evidence clauses.
“This book describes data structures from the point of view of functional languages, with examples, and presents design techniques so that programmers can develop their own functional data structures.”

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
