          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
          Assignee: nobody at puremagic.com
          Reporter: moonlightsentinel at disroot.org

__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.
