💻 Code

// This is JavaScript, not TypeScript
function A() {} // define A with class syntax leads to the same results

Object.defineProperty(A.prototype, "m", { value: function m() {}, writable: true, configurable: true });
const a = new A();

a.m()

🙁 Actual behavior

TypeScript identifies m as a method, but says it has no call signatures: Type '{}' has no call signatures.

🙂 Expected behavior

TypeScript allows a.m().

Reproduce el comportamiento del TypeScript Playground enlazado usando el ejemplo de JavaScript y, después, sigue cómo se gestiona Object.defineProperty durante la comprobación de tipos. Se considera terminado cuando TypeScript reconoce la propiedad definida como invocable, de modo que a.m() pasa correctamente la comprobación de tipos.
