From @jimav

This is a bug report for perl from jim.avera@gmail.com,
generated with the help of perlbug 1.40 running under perl 5.26.1.

use v5.25;
use Data::Dumper;
my $foo = [1..5];

print Data::Dumper::Dump([$foo], [qw(foo)]); # works

say Data::Dumper::Dump([$foo], [qw(foo)]); # does NOT work

The "say" line dies with
Not a HASH reference at /usr/lib/x86_64-linux-gnu/perl/5.26/Data/Dumper.pm line 231

The code there is as follows:

226 sub Dump {
227 return &Dumpxs
228 unless $Data::Dumper::Useperl || (ref($_[0]) && $_[0]->{useperl})
229
230 # Use pure perl version on earlier releases on EBCDIC platforms
231 || (! $IS_ASCII && $] lt 5.021_010);
232 return &Dumpperl;

Data::Dumper line 228 looks suspect:

because in the documented use case
Data::Dumper::Dump(...)
there is no object.

Probably the code should test for ref($_[0]) eq "Data::Dumper" or something similar which deals with derived classes

But... why ddoesn't this cause a problem when using "print"? What does "say" do which provokes the error?

Dump is not a sub. It's a method.

This is strange. None of these lines work for me with 5.26.0, like I
would expect.
What's working though is this line:

Data::Dumper->Dump([$foo], [qw(foo)]);

And this works with both `say` and `print`. This is how it's
documented.

If this works for you:

print Data::Dumper::Dump([$foo], [qw(foo)]); # works

then it would be interesting to debug that.

Ach. YABBR (Yet Another Bogus...)

You are right of course. I really shouldn't work so late.

Please close.
