          Issue ID: 23244
           Summary: [REG 2.100.1]Functions with function parameter give
                    strange error messages
           Product: D
           Version: D2
          Hardware: All
                OS: Windows
            Status: NEW
          Severity: regression
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com

Following code displays strange error messages on dmd 2.100.1 (current stable
branch):

------------------------------------------------
void main()  safe {
    ubyte[] bin(ubyte[] dat...) { return dat; }
}
------------------------------------------------

Error: typesafe variadic function parameter `dat` of type `ubyte[]` cannot be
marked `return`


Even though there is actually no return mark, the error message points out as
if it is marked.

Also, this error does not occur in 2.100.0.
Even if this error is legitimate, there should be a period of time during which
it is deprecated, rather than suddenly making it an error.
