in reply to Data::Dumper too noisy

How about monkey-patching Data::Dumper?
use Data::Dumper; use DateTime; use DateTime::TimeZone; use Math::BigInt; $var = { number => 1, bigint => Math::BigInt->new(), datetime => DateTime->now(), tz => DateTime::TimeZone->new( name => 'America/Chicago' ), }; $Data::Dumper::Useperl = 1; *Data::Dumper::_dump_orig = \&Data::Dumper::_dump; *Data::Dumper::_dump = sub { return "Math::BigInt->new('".$_[1]->bstr()."')" if ref $_[1] eq 'Math::BigInt'; return "rfc822('".$_[1]->strftime("%a, %d %b %Y %H:%M:%S %z")."')" if ref $_[1] eq 'DateTime'; return ref $_[1] if (ref $_[1]) =~ /^DateTime::TimeZone::/; goto &Data::Dumper::_dump_orig; }; print Dumper($var);
Running it returns this:
$VAR1 = { 'bigint' => Math::BigInt->new('0'), 'number' => 1, 'tz' => DateTime::TimeZone::America::Chicago, 'datetime' => rfc822('Wed, 03 Dec 2008 04:12:53 +0000') };
Note that most people would prefer that you subclass Data::Dumper to do the same thing, but this works if you need something quick and dirty.
