Yesterday I ran into a #TypeScript challenge which I could not solve. I want a
generic wrapper function, which preserves the return type of the passed wrapped
function:

The point is to not define the return type when creating an instance of the
wrapper, which would solve it for each use case:
const retry5string = retry<string>(5) const retry5number =
retry<number>(5)
