[dancer-users] D1 => D2 request->referer in LIST context has changed

[Gabor Szabo]

If there is *no* referrer then

@z = request->referer;   used to return an 'undef'

Now it returns and empty list.

This blew up in my code that had

%h = (
    ref => request->referer,
    ....
);

so I'll have to replace that code with

%h = (
    ref => scalar request->referer,
    ....
);

or with

%h = (
    ref => ( request->referer // ''),
    ....
);


I understand that the D2 behaves "more correctly" than D1 did, but I'd like
to verify.
Is this change is also intentional? Could you point out where else has this
change happened?

regards
  Gabor
