          Issue ID: 20619
           Summary: ddox documentation "auto auto" return values
           Product: D
           Version: D2
          Hardware: x86
                OS: Windows
            Status: NEW
          Severity: minor
          Priority: P1
         Component: dlang.org
          Assignee: nobody@puremagic.com
          Reporter: john.michael.hall@gmail.com

The ddox documentation has some functions (see [1] and [2]) with return values
of "auto auto". However, this does not happen with the other documentation (see
[3] and [4], respectively).

While I noticed this issue within the std.conv package, it is not limited to that and a google search for "auto auto" site:https://dlang.org/library/ reveals 220 results. Looking at a few of these issues, it appears that this happens when there are no attributes in the functions.  I did not see an example of this when it is a non-templated function, but I did not look that hard. I did not see the issue when looking at other functions in phobos that have attributes.
