## What it is
Async++ is a lightweight concurrency framework for C++11 providing asynchronous tasks, continuations, and parallel algorithms. It is inspired by Microsoft PPL and the N3428 C++ standard proposal.

## Use cases
- run tasks asynchronously in C++11
- chain task continuations with then()
- execute parallel for loops and reductions
- invoke multiple functions in parallel
- wait for multiple tasks with when_all
- schedule work across a thread pool

## When to choose
- you need lightweight async/parallelism without heavy dependencies
- you are limited to C++11 and want PPL-style tasks
- you need cross-platform support including Linux, macOS, Windows, and iOS

## When to avoid
- you can use C++17/20/23 std::execution, std::future, or coroutines instead
- you need GPU or heterogeneous parallelism
- you need a full-featured threading framework with executors and cancellation

## Facets
- artifact type: library
- maturity: maintenance
- function: concurrency
- domain: developer-tools, cross-platform
- platform: windows, cpp
- tags: cpp11, task-based-parallelism, parallel-algorithms, ppl-inspired, linux, macos, ios
