stealing _dump was my first hunch too, but is that is called on (sub)values, it will be very hard to catch the *total* size. And you will have to force using Dumpperl (a.o.t. using the much faster Dumpxs).
{ my $size = 0;
my $org_dump = \&Data::Dumper::_dump;
sub Data::Dumper::_dump
{
$size >= 4000 and return "";
my $s = $org_dump->(@_);
$size += length $s;
return $s;
}
}
could be a crude start ...
