## What it is
A Go library providing a concurrency-limiting goroutine pool that caps the number of concurrently executing tasks while allowing unlimited task queuing without blocking submissions. It offers a simple Submit/StopWait API for parallel task execution.

## Use cases
- limit concurrent goroutines in go
- process tasks in parallel with bounded concurrency
- submit many jobs without blocking the caller
- worker pool for go tasks
- throttle parallel http requests in go
- run background jobs with fixed worker count

## When to choose
- you need non-blocking task submission with unlimited queueing
- you want a small, dependency-free Go worker pool
- you only need to limit concurrent execution, not queue size

## When to avoid
- you need backpressure that blocks when all workers are busy (use gammazero/workers instead)
- you need distributed workload processing or persistent job queues
- you need bounded queue size or task prioritization

## Facets
- artifact type: library
