Crash when Root Composer.json has no name

[Hanmac]

Describe the bug

Some Projects doesn't have a name themselves:

PHP Fatal error:  Uncaught Error: Typed property ComposerUnused\ComposerUnused\Composer\Config::$name must not be accessed before initialization in /var/www/vendor/icanhazstring/composer-unused/src/Composer/Config.php:26

while composer does this:

#composer why symfony/form
__root__                                 dev-master requires  symfony/form (5.4.*)

imo unused could also use this as default value

[icanhazstring]

It was fixed recently with a better error message.

But you are right, we could silently fall back to root as a name. But then your configuration also has to reference that name to add additional files to it.

But I can think about that. Thanks 👍
