💻 Code

class Person {
    ["B"](a: number): string;
    ["A"](a: string|number): number | string {
      return 0;
    }
}
let p = new Person();
p.A(0)

// Runtime erorr
p.B(0)

🙁 Actual behavior

Runtime error, on p.B since that member does not actually exist.

🙂 Expected behavior

Compile time error when declaring overloads on methods with computed names and the overload names don't match

Notes

• Seems to happen with other types of computed properties such as symbols.
• Was not found in actual code I was just tinkering with isolatedDeclarations.
