Announcer>>on: aClass doOnce: aBlock

I'm still a couple of versions behind hacking like crazy an MVP

Once I make the upgrade to latest code, and upgrade myself to the new workflow, I'll start sharing via pull request yeah

We're going to have a StartupWeekend later this month, so I'll let that upgrade for after the event.

Look, you'll find me among mentors here:
