#466

Thanks for the contribution 🙏

1. Please add changeset by instruction in README. It will be used to determine the next version of the library and would be filled to CHANGELOG.
2. Please mark your changes in docs. At least in API ref with a mention that this overload is available since the next minor release (0.13 I assume).
3. I see type-tests for the change, but I do not see any runtime-test. Could you add it to ensure your changes are working correctly? We do not accept PRs without tests.

Shall we introduce the same change for createQuery?

Does it worth changing?

// before
const mut = createMutation({ handler })

// after
const mut = createMutation(handler)

It's only removing brackets. Why is this important?

I believe it's better to start with an RFC accordingly to https://github.com/igorkamyshev/farfetched/blob/master/CONTRIBUTING.md 🙏

createMutation({ handler: service }) vs createMutation(service). Usually you have many services in your model

yes
