My point is not the types/monadic constructs, etc (I love to do functional jerk off as a guy next to me, though), but that there are ways to keep code readable and straightforward without neither invocation chains

DoOne().OnError().ThenDoTwo().ThenDoThree().OnError()

nor coloring/await mess, nor golang-style useless error handling noise
