          Issue ID: 18972
           Summary: __traits(getOverloads) example with 3rd argument
                    doesn't compile
           Product: D
           Version: D2
          Hardware: x86
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dlang.org
          Assignee: nobody at puremagic.com
          Reporter: dkorpel at live.nl

https://dlang.org/spec/traits.html#getOverloads
"The third argument is a bool, and is optional. If true, the result will also
include template overloads."

When I try this by running the example I get this:

onlineapp.d(27): Error: expected 2 arguments for getOverloads but had 3

Line 27 is:
```
27  foreach (t; __traits(getOverloads, D, "bar", true))
28      writeln(t.stringof);
```

I don't know whether it's the spec or implementation, but one of them is
incorrect.
