Modifying a non-pointer receiver in example

The example is modifying a non-pointer receiver's field. It seems like a bug.

The aim here was to simulate a sort of top-down functional approach similar to React in how it accesses state at a field-level but mutates it indirectly:

this.setState({ Cocos: [...this.state.Cocos, '🥥'] })

But I'm more than open to considering a pointer style of mutation that is more Vue-like and 2-way bound. That might even feel more idiomatic in Go. Thanks for pointing this out!
