# 44-haskell-seq-queues

This example shows FIFO retry batching with `Data.Sequence`.

It includes:

- one queue of retry requests backed by `Seq`,
- functions that append retries and take the next batch in order, and
- a test suite run by `nix flake check`.

Useful commands:

```bash
nix develop
cabal run
cabal run -- 3
cabal test

nix build
./result/bin/mini-seq-queues 3

nix run . -- 3
nix flake check
```
