@lukastaegert I'm wondering if this is a right way to solve this problem, using the class name instead of renderName in the static block, as shown in the following code.

let Test$1 = class Test {
  static test = 'Test1';
  static { console.log(Test.test); }
};

Yes, I think that should work.

I realized that keeping name on static block is maybe not enough, it should probably be kept on non-static block also. For example would give this as a result if the fix is done only on static block (so an error would be raised):

let Test$1 = class Test {
  constructor() {
    console.log(Test$1.test);
  }
  static test = 'Test1';
  static {
    console.log(Test.test);
    new Test();
  }
};

The name should probably be also be kept everywhere inside the class:

let Test$1 = class Test {
  constructor() {
    console.log(Test.test);
  }
  static test = 'Test1';
  static {
    console.log(Test.test);
    new Test();
  }
};

I am not sure that the PR is taking this into account.

Oh, thanks! I didn't take this into account, I'll fix it later in the PR.
