I don’t think that there is at the moment.
It might be possible to mark a PDL read-only to prevent modification of its
contents, but modification as you describe involves a Perl-level change to the
variable: putting a new value in the variable is not something that PDL
controls.
You could make a Perl copy of the PDL and hand *that* off:
$tmp = $my_pdl;
untrusted($tmp);
