Greetings ... please consider the following mini-script, which concerns the placement of a PDL value inside a vanilla Perl hash:

use strict;
use PDL;
use PDL::NiceSlice;

my %h;
my $PDL_value = zeroes(3,1);
$h{'keyval'} = $PDL_value;

my $dbg;
[download]

========================
Now, if we run this as "perl -d:ptkdb sample.pl" and:

• set a breakpoint at the final line ("my $dbg;") and run to the breakpoint
• place "%h" in "Enter Expr:"

The debugger will crash, yielding the error message: Hash given as a pdl - but not {PDL} key! at c:/Perl/site/lib/Devel/ptkdb.pm line 2619.

It turns out that the message "Hash given as a pdl - but not {PDL} key!" (not surprisingly) comes from within PDL itself, not ptkdb. Is there an effective workaround for this problem which makes it possible to debug code with hashes which contain PDL objects?

TIA ...
