👨‍💼 Turns out the concept of creating a temporary session value is pretty common. So common in fact that there's a pattern and an API for handling this.

The pattern is called the "flash" pattern. It's a temporary session value that is meant to be displayed to the user and then removed.

Right now what we're doing can be represented like this:

set -> commit -> get -> unset -> commit

With the flash pattern it looks like this:

flash -> commit -> get -> commit

When you use session.flash it automatically unsets the value after the next get of that value.

So what we can do is change our set call to flash and then we don't have to worry about calling unset anymore. So go ahead and make those updates and we'll be in a good spot.

It's important to note that we do still need to commit the session because it is being changed. This isn't a web standard API or anything. This is just a common pattern that people use.
