Instead of writing nested isinstance checks or using Python's built-in singledispatch (which only works on the first argument), you annotate each version of your function with its type signature and ovld routes calls to the right implementation.\n\nThe library handles single and multiple arguments, supports value-based dispatch through Literal types and custom dependent types, and works with methods via metaclasses or base classes. It also provides variants (specialized copies of a function) and medleys (composable mixin-like classes), making it useful for recursive data structure traversal, serialization, and other polymorphic patterns.","worth_installing":"Yes. Ovld has no dependencies, installs cleanly, is actively maintained, carries an MIT license with no restrictions, and solves a real problem\u2014writing cleaner polymorphic code than isinstance chains. It's suitable for production use if you need multiple dispatch."},"id":"ovld","links":{"html":"https://skillfed.io/packages/ovld","md":"https://skillfed.io/packages/ovld.md","pypi":"https://pypi.org/project/ovld/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-05-14","license_spdx":"MIT","license_treatment":"permissive","name":"ovld","python_support":"supports_current","summary":"Overloading Python functions"},"popularity":{"monthly_downloads":586966,"position":5878,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.5.17"}
