Suppose I new an object. Is there a way to get the class name from the
reference to the object?

The ref() function should return the name of the package of the
object - I guess that's what you mean by "class name".

#!/usr/bin/perl -l

use Data::Dumper;

use Scalar::Util qw(
blessed
reftype
);

my $object = bless [], __PACKAGE__;

sub info { Dumper \@_ }

my $i;

print ++$i, ":\t", $_ for
$object->info(),
Dumper ( $object ),
ref ( $object ),
blessed( $object ),
reftype( $object ),
;

__END__
