(...args: never) => void signature throws an error in TS 5.1 #54543
Description
If I have a function with the signature of (...args: never) => void, TypeScript 5.1 now throws this error:
Argument of type '[]' is not assignable to parameter of type 'never'.
Previous versions of TypeScript allows me to call the function without any parameters.
Is this intended behaviour? I don't believe seeing anything in the changelog mentioning this.

This is intended, see: #52387

Note that it still works fine if you use
(...args: never[]) => voidinstead (and it makes a bit more sense, because rest arguments are supposed to have an array/tuple type).typescript-bot commentedon Jun 9, 2023
