Who's relying on that CPAN release?
Sometimes it's useful to know who exactly is relying on your CPAN distribution - for example, if you're planning an incompatible API change for a module, and wish to contact people using it to give them advance notice. MetaCPAN handily includes a "reverse dependencies" link for every distribution. However, sometimes that might not be enough; you may want recursive results. In which case you need to dig around in the MetaCPAN API.
Thankfully there's a little module called MetaCPAN::API that helps you do just that. Here's how I've used it (plus Moo) to retrieve recursive dependencies starting at a seed...
