研究方向

This issue is blocked by yargs/yargs#846, which must be resolved first. Once that is done, the feature can be implemented by modifying meow's handling of the `isMultiple` option to support comma separated values. Refer to the linked yargs issue for the expected behavior and inspect meow's source code in `index.js` for the current implementation of option parsing.
