Checks if modules failed and notifies the community.
Just thinking out loud here.
A module turns out to fail today. It didn't fail yesterday. The bot reacts by telling the channel.
For each such new failure, as part of the failure message, the bot should also report what since yesterday has changed: the module, Rakudo, NQP, the underlying VM, or any combination of these.
Also as part of the failure message, the backend(s) should be reported.
Many modules fail today that didn't fail yesterday. The bot tells the channel, but without flooding the channel; it links to a text file with a list of failing modules.
A single module or a group of modules that still fail for the Nth day in a row should also be flagged up, but with separate messages.
Optionally, the bot might want to keep track of a module's previous failure history, at least (say) 100 days back, and (if there was a previous period of failures for that module) also report the number of previous failures.
Important: the bot shouldn't feel spammy. It's OK for IRC lines to be longish, but there shouldn't be more than two spontaneous utterances per day, and preferably only one.
When asked directly, the bot can give full information about the current status of a module.
Very low-priority, but still possibly relevant in the future: if/when we expand beyond just Rakudo Star modules, the bot should also include information about whether or not the module is a Rakudo Star module.
