How to Use OCaml's Coercion Operator
Lecture, Tutorial
- The speaker plans to explore OCaml's subtyping relation over the course of two videos.
- Following the subtyping discussion, the speaker intends to examine immutable arrays specific to Jane Street.
- The speaker anticipates that immutable arrays possess a feature connected to the discussed subtyping relation.
- It is expected that most programmers will utilize the fully explicit coercion notation in practice.
- The coercion operator is predicted to be guaranteed free at runtime with no impact on performance.
- The operator performs only type checking and executes no operations during runtime.
- The coercion operator is expected to maintain consistent efficiency.
- The speaker expects to cover the interaction between the coercion operator and variant annotations during new data type definitions in the subsequent video.
