  Fri Mar 04 14:18:39 2016 KENTNL [...] cpan.org - Ticket created
Subject: DWarn with empty @arglist profoundly confusing.

Was just fooling around and managed to accidentally stumble into this:

 perl -MDevel::Dwarn -e 'my (@items); Dwarn @items;'
Warning: something's wrong at <...>/Data/Dumper/Concise/Sugar.pm line 20.


( case furnished slightly to give a semi-real situation where you could encounter it )

 perl -MDevel::Dwarn -Mstrictures -d:Confess -e 'my (@items)=(1,2,3); Dwarn @items and shift @items for 0..3'

 

When `@items` becomes empty, `Dwarn` regresses to printing (abridged, with -d:Confess added):

Warning: something's wrong at <...>/Data/Dumper/Concise/Sugar.pm line 20.
    Data::Dumper::Concise::Sugar::DwarnL() called at <...>/Data/Dumper/Concise/Sugar.pm line 15
    Data::Dumper::Concise::Sugar::Dwarn() called at -e line 1

I would suggest the right thing to do here would be emit "()" in such a condition, but not entirely sure.

I agree, an output of `()` seems best to me. On Fri, Mar 4, 2016 at 11:18 AM, Kent Fredric via RT < bug-Data-Dumper-Concise@rt.cpan.org> wrote: Show quoted text
