That's all for our `poke-noun` arm. But what about when the timer goes off? Behn will create a `gift` a similar construct to how we created an `effect`, only this time it will end up being dispatched back to us by Gall in the `++wake` arm. Gall looks for an arm named `++wake` when a timer goes off; it is defined this way in the vane's code. Gall will actually check for an arm that also contains the wire name, but this will be covered in a later document. So any app that wants to use a timer trigger needs to have an arm called `++wake`.
