Bleeding edge 🔪

• Check that each trait is used and analysed at least once - level 4 (https://github.com/phpstan/phpstan-src/commit/c4d05276fb8605d6ac20acbe1cc5df31cd6c10b0)
• Check that PHPStan class in class constant fetch is covered by backward compatibility promise (https://github.com/phpstan/phpstan-src/commit/9e007251ce61788f6a0319a53f1de6cf801ed233)

If you want to see the shape of things to come and adopt bleeding edge features early, you can include this config file in your project's phpstan.neon:

includes:
    - vendor/phpstan/phpstan/conf/bleedingEdge.neon

Of course, there are no backwards compatibility guarantees when you include this file. The behaviour and reported errors can change in minor versions with this file included. Learn more
