in reply to Looking for a CPAN namespace

Vaguely similar modules include Device::Cdio::ISO9660::IFS and IO::DiskImage::Floppy, so those are potential candidates.

Personally I'm of the opinion that virtually nobody browses the CPAN by namespace any more, so top-level names are cheap.

package Cow { use Moo; has name => (is => 'lazy', default => sub { 'Mooington' }) } say Cow->new->name
