Episode notes

The way that Mojo works is that the call to that function, which happens in the accept block, calls a function. And then instead of returning nothing, it actually returns something between nothing and an error. So when you get to the call, you say, okay, cool, I call the function. Hey, I know locally I'm in a try block, right? And so I call thefunction and then I check to see what it returns. Aha, if it's that error thing, jump to the accept block.
