Sometimes your in bed and want to watch a YouTube video . Maybe that ' s just me . I ' m not going to go look for my headphones or turn on my stereo system for that . <| sep |> Why don ' t you fix the actual problem ? <| sep |> It ' s funny that you ' d expect that move from Ricky D , but not from Bob . That being said context is important here Bob Sura had recorded backtoback triple doubles in the previous 2 games , and he was 1 rebound away from recording his 3 rd . That being said , still a bush league move hahaha <| sep |> That ' s how I interpret their mention of lambda calculus otherwise , it ' s just replacing one formal foundation with another , which doesn ' t help with notation . Lambda calculus just gives a more precise notation for bindings , which is something mathematical notation routinely screws up . You can express noncomputable things just fine with lambda calculus notation , specifically using higher order abstract syntax this what is done in HOL for example . Replacing one formal foundation with another indeed doesn ' t really help the significant notational problems . But trying to construct a formalism yourself in type theory or anything else is a great way to understand it better . That ' s why I was saying that the blame is misplaced The author is frustrated by not understanding the mathematics well , but this is just a result of poor teachinglearning of mathematics , not really much about the notation . although , if lambda calculusHOL style notation were used in this example it would be far less confusing
