I am not sure if this is fixed in master, but I noticed this in
pidl/lib/Parse/Pidl/Samba4/NDR/Parser.pm:

sub ParseArrayPullGetSize($$$$$$)
...
        $self->pidl("size_$e->{NAME}_$l->{LEVEL_INDEX} = $size;");
        my $array_size = "size_$e->{NAME}_$l->{LEVEL_INDEX}";

        if (my $range = has_property($e, "range")) {
                my ($low, $high) = split(/,/, $range, 2);
...
                $self->pidl("\treturn ndr_pull_error($ndr,
NDR_ERR_RANGE, \"value out of range\");");

It would be nice if this last had something like:

   \"value %u out of range $low..$high\", $array_size

Giving us more informative error messages is useful. It seems that the
range property appears in lots of places, so it would be nice if there
was more info on a failure to parse a field that had a range
attribute.
