This check compares calls to functions or methods with their respective definitions.
If the call has less 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. Please note the @ignore annotation hint above.
