Bug introduced by Lucas Michot
The method isEmpty() does not seem to exist on object<Spatie\Collection...ros\Macros\SliceBefore>.

This check looks for calls to methods that do not seem to exist on a given type. It looks for the method on the type itself as well as in inherited classes or implemented interfaces.

This is most likely a typographical error or the method has been renamed.

Unused Code introduced by Lucas Michot
The call to SliceBefore::__construct() has too many arguments starting with array(new static(array($this->first()))).

This check compares calls to functions or methods with their respective definitions. If the call has more arguments than are defined, it raises an issue.

If a function is defined several times with a different number of parameters, the check may pick up the wrong definition and report false positives. One codebase where this has been known to happen is Wordpress.

In this case you can add the @ignore PhpDoc annotation to the duplicate definition and it will be ignored.

Bug introduced by Rias
The variable $previousItem does not exist. Did you forget to declare it?

This check marks access to variables or properties that have not been declared yet. While PHP has no explicit notion of declaring a variable, accessing it before a value is assigned to it is most likely a bug.
