How to implements 'this' keyword in with langium ?

[hyphappy011]

I copy the langium-lox example, and write some code with a simple class in the playground, but it can not deal the "this" keyword.
How can i fix it?

class testClass {
  name: string

  testIt():void {
     this.name = "123";
  }
}

Hey @hyphappy011,

to support the this keyword correctly, you would need to implement a specialized scope provider. You can find a general guide on it here. Unfortunately, the Langium playground doesn't offer to define a new scope provider, and the default scoping doesn't cover this kind of advanced use case.
