<!--
Depending on the installed PHP version, Composer will allow packages using
PHP 7.4 or 8.0 syntax. Psalm, however, will use the minimum PHP version defined
in the composer.json for its parser (which is currently PHP 7.2), therefore we
have to specify "7.4" here to make Psalm understand arrow functions.
