Overview

furqan-lint is a structural-honesty linter for Python, Rust, and Go that catches a class of latent defects falling outside the coverage of ruff (style), mypy (declared types), and conventional security and dependency tooling. — furqan-lint: The Structural-Honesty Checks ruff and mypy Do Not Catch, Across Python, Rust, and Go (White Paper v1.0) (2026)

Fixed CI: Fixed lint job to install project dependencies for mypy Code Style: Applied ruff and black formatting fixes Type Checking: Resolved mypy type errors in examples; export AsyncINE from package — randsley/pyptine: v0.3.3 (2026)

See also Typing cheat sheetA quick overview of type hints (hosted at the mypy docs) Type System Reference section of the mypy docsThe Python typing system is standardised via PEPs, so this reference should broadly apply to most Python type checkers. (Some parts may still be specific to mypy.) Static Typing with PythonType-checker-agnostic documentation written by the community detailing type system features, useful typing related tools and typing best practices. — typing — Support for type hints — Python 3.13.18 documentation (1999)

The study reveals eight patterns-of-use for the dynamic type, which have implications for future refinements of the mypy type system and for tool support to encourage precise type annotations. — Toward a Corpus Study of the Dynamic Gradual Type (2025)
