TypeScript

Summary At the moment typescript only allow the following signatures for SetStoreFunction interface; I'm hidding the type because it's not relevant for the discussion. Said another way, at the moment, the interface only allow for: exactly 1 arg exactly 2 args exactly 3 args exactly 4 args exactly 5 args exactly 6 args exactly 7 args exactly 8 args 8 or more args. My proposition is to add overload for the cases: 1 or more args 2 or more args 3 or more args ... 7 or more args So that it would be legal to write : Breaking change: Adding support for those cases means that this does not error anymore The reason for that is that the rest of the overload 1+ typing is not smart enough to inspect the second argument so it thinks that he is looking at a . I say it is not a big deal to lose this safety and it was a safety we didn't provide for case 8+ before my change anyway. How did you test this change? Commented the 2 failing tests Added some test for the new signatures pnpm test
