          Issue ID: 22868
           Summary: __traits(parameters) returns parameters of delegate
                    instead of function
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: major
          Priority: P1
         Component: dmd

__traits(parameters) currently yields the parameters of the delegate when the foreach iterates over an aggregate using opApply. This is wrong and leaks an implementation detail into user code.
