描述

const p1 = 0;
const p2 = 1;
class A {
  [p1] = 0;
  [p2]() {}

研究方向

Investigate the TypeScript compiler's emit phase, specifically the transformer that handles computed property names in classes. The relevant code is likely in src/compiler/transformer.ts or src/compiler/emitter.ts. Review the issue comments for any pointers or suggested fixes. The bug manifests when a computed property name is used both as a data property and a method, causing verbose output.
