Putting logic in shuffles?

Hi All,

I'm v new to ink and I'm wondering is there a way to perform logic based on the outcome of a shuffle?

I feel like I'd want to be able to do something like this

```
VAR holding_item = false
{~He hands me a cup of coffee {holding_item = true} | He hands me the newspaper {holding_item = true}}
```

Although it feels like the markup is encouraging me to do it more like this

```
VAR holding_item = false
{~He hands me a cup of coffee {set_bool(holding_item, true)} | He hands me the newspaper {set_bool(holding_item, true)}}

== function set_bool (bool, state)
~ bool = state
```

I read all the documentation and searched these topics but I couldn't quite tell what was the proper way to do this. Any help appreciated!
