描述

A decorator would be perfect for this.

I'd like to wait until the Decorator proposal is stage 3 though.

Example:

const lazy = require('define-lazy-prop/decorator');

class Unicorn {
	@lazy rainbow() {
		return 'Lazily computed value';
	}
}

研究方向
First, understand how `define lazy prop` works by examining its source code (likely in index.js). Then, research the current status of the JavaScript decorators proposal (stage 3) and implement a decorator that applies the lazy property definition to class methods. The example in the issue shows a `@lazy` decorator on a method. Check the comments for any additional context or implementation hints. No linked PRs exist, so the implementation is open.
