PROFILE
Alley Stoughton
Alley Stoughton contributed to the EasyCrypt/easycrypt repository by developing features and fixes that enhanced type safety, API flexibility, and proof reliability. Over three months, Alley exposed internal type policies and theory creation APIs, enabling external tools to perform type checking and manual theory management without loaders. Using OCaml and functional programming techniques, Alley improved module interfaces and streamlined the require workflow for maintainability. Alley also introduced new lemmas for reasoning about list concatenation, refined operator pretty-printing, and clarified error messages, addressing both correctness and developer experience. The work demonstrated depth in compiler development, type systems, and formal verification within a complex codebase.

Jan 1, 2025January 2025 — EasyCrypt/easycrypt monthly summary. Key features delivered: - Exposed the tp_nothing typolicy from EcTyping in ecTyping.mli, enabling external tools to perform type checking and explicitly forbid type variables (commit bba51946f0b8a17a39878ecbd4875fa65ebb62d4). Major bugs fixed: - No documented bugs fixed for this month. Overall impact and accomplishments: - Strengthened external tooling integration and type-safety by making EcTyping's policy explicit in the public interface, paving the way for automated checks and safer interoperability with third-party tools. Technologies/skills demonstrated: - Interface design and module boundary exposure, type policy modeling, commit-driven development and version-control discipline.
