Code Inspection: Unused 'match' condition

Reports the conditions in match expressions that will never be matched.

Similarly to PHP Engine behavior, the inspection uses strict comparison ( === ) to check the types in match conditions against the match argument type, regardless of the strict_types directive. Since no type coercion occurs, some conditions may be non-matched due to non-matching types.

See Match expression ( for details.
