I'll take a look at this if nobody else steps up.  It might just
be a minor change to this part of plperl.c:

210     "    else " \
211     "    { " \
212     "      my $str = qq($elem); " \
213     "      $str =~ s/([\"\\\\])/\\\\$1/g; " \
214     "      $res .= qq(\"$str\"); " \
215     "    } " \

Does the current implementation provide automatic conversion to a
Perl array for inbound values?  Unless I'm missing something that
entire problem might still need to be solved.
