I have something similar to the following:

const test = new TestCase();
console.log(test.name);

const itm = new TestItem();
console.log(itm.name);

The problem is test.name actually calls TestItem's getter method. The same code works properly with standard TypeScript. You can see it running properly with a full test case on the TypeScript Playground.

I am using TSTL 0.32.0 with TypeScript 3.8.3. The code works fine with 0.31.0.
