What Does Handling It Later Look Like

So one of the things I'm curious about is like, so you mentioned like, hey, let's, let's handle it later. Do you mean like you get an error somewhere? You literally like pause execution. So what does handle it later look like specifically? Is it like at some point in your code, you have a conditional and do something different? Or are there other ways to deal with this kind of thing that we don't talk about yet?
