@SimenB Awesome! Thanks 😄 |

Hey @SimenB. I thought about this PR a bit over the past two days and have concluded that we shouldn't merge it. I think the maintenance cost is higher than the value it provides. For these functions, when they are invoked improperly, Jest will simply throw and crash the test. I think that is ok. The alternative here is to surface such mistakes earlier but at the cost of us having to maintain this API changes in two places. I'd prefer to not take on this cost right now but I'm happy to consider different viewpoints and may reopen if you feel strongly that we should do this. |
