Returns is a functional programming library for Python that provides type-safe containers for managing state, error handling, and optionality. It serves as a monadic container library and a type-safe error handling framework, replacing traditional try-catch blocks and null checks with Result and Optional containers to treat exceptions as data. The project is distinguished by its use of a specialized Mypy static analysis plugin to validate functional pipelines and emulate higher kinded types. It provides mechanisms for isolating side effects through IO containers and offers a framework for typ

This project is a functional programming library and toolkit for building production TypeScript applications. It provides a system for managing concurrency, error handling, and resource lifecycles using functional effects. The project distinguishes itself through a comprehensive suite of specialized toolkits, including a dependency injection framework for decoupling service implementations, a workflow orchestrator for coordinating durable processes, and a SQL database toolkit for consistent data operations across multiple dialects. It also implements an OpenTelemetry instrumentation library f

more-itertools is a Python iterable utility library providing advanced functions for manipulating, filtering, and transforming data sequences. It serves as a data stream processing toolkit and a set of utilities for iterator state management, extending the capabilities of the standard Python itertools module. The library includes a combinatorial math toolkit for generating permutations, combinations, and powersets, alongside routines for number theory calculations and matrix operations. It also provides tools for stream state management, allowing users to peek at upcoming elements or seek wit
