Bug#912780: Line numbers not printed on error despite XML_LIBXML_LINENUMBERS => 1
Wow that Carp::Always makes things much better. Do make a note about it on the man page or something, at the same time mentioning how it is different that other thing... Thanks.

So you're indeed looking for code line numbers, not document line numbers.
Again, the XML_LIBXML_LINENUMBERS feature is about the latter.
Maybe try Carp::Always or something.
% cat e.pl
#!/usr/bin/perl -w
use strict;
use Carp::Always;
use XML::LibXML;
my $doc = XML::LibXML::Document->new( XML_LIBXML_LINENUMBERS => 1 );
my $x = $doc->createElement('x');
$x->appendChild($x);
exit 0;
% perl e.pl
appendChild: HIERARCHY_REQUEST_ERR
at e.pl line 8.
Leaving this open as I don't see where XML_LIBXML_LINENUMBERS is
documented. XML::LibXML::Parser is quite clear about the equivalent
line_numbers() method though.
If this option is activated, libxml2 will store the line
number of each element node in the parsed document. The line
number can be obtained using the "line_number()" method of the
"XML::LibXML::Node" class (for non-element nodes this may report
the line number of the containing element). The line numbers
are also used for reporting positions of validation errors.

Well all I know is I want it to say something like

Not sure what you expected to get, the offending line in the code
perhaps?
It looks to me like this feature is about reporting line numbers
in parsed XML documents, and you're not parsing anything.
