No, the methods defined with "=" are automatically moved into the 
constructor, so that they are created once for each new instance. `this` 
in the arrow function would in fact be bound to the instance.

It's indeed super-confusing to "declare" such methods right inside the 
`class` though, that's why I'm really opposing that proposal 
(https://github.com/jeffmo/es-class-static-properties-and-fields).
