## Composer does not check class ambiguity properly

- If you have class duplicate in your project, composer may not warn about that.

  - This repository shows an example of that.

  - Since composer 2.8, you can use `--strict-ambiguous`, but that still does not solve this issue

- Currently, you can ensure no ambiguity is present by [shipmonk/name-collission-detector](https://github.com/shipmonk-rnd/name-collision-detector)

### How to reproduce

```sh

composer install

composer dump -a --strict-ambiguous

echo $?

php run.php

```

### How to see all real collisions

```sh

composer require --dev shipmonk/name-collision-detector

vendor/bin/detect-collisions src tests

```
