Pull Request Overview
This PR introduces a new analyzer rule, ThrownExceptionNotInFunction, to detect cases where an exception is thrown directly as a function argument instead of wrapping it in a function literal. It includes:
- Implementation of the new analyzer rule scanning for thrown exceptions used in place of functions.
- Registration of the rule in the
AnalyzerPlugin. - Comprehensive tests covering method calls, constructors, multiple argument lists, and indirect exception-throwing scenarios.
