Question

A parody of Smokie’s “Living Next Door to Alice” titled for these concepts was performed at NDC Oslo 2019, in which the singer and audience occasionally shout “What the fuck are [these things]?” A Brent Yorgey blog post coined the term “[this word] tutorial fallacy” in criticizing (15[1])many tutorials (15[1])to this concept (15[1])for their poor pedagogy and strained analogies, such as comparing these concepts to burritos. (15[1])A 2003 talk by the co-creator of a certain programming language noted that “our biggest (15[1])mistake” was using a “scary term” for this concept instead of “warm, fuzzy thing”. Saunders Mac Lane’s book (*) Categories (-5[1])for the Working Mathematician (10[1])is the source of a famous quip (10[1])about this term, namely that this thing “is a (10[1])monoid (10[1])in the category of endofunctors”. For 10 points, name this functional programming construct that supports two operations called “return” and “bind”, and is used to model side effects in Haskell. ■END■
