If you open the a.tgz using Archive::Tar->new(), it appears you could use get_content to retrieve the contents of the internal tar, and then use Archive::Tar->new(data=>...) to open it. Repeat this to access the files further in. I haven't actually done this, but it looks possible based on the docs. It could potentially take up a great deal of memory.
