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 many tutorials to this concept 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 mistake” was using a “scary term” for this concept instead of “warm, fuzzy thing”. Saunders Mac Lane’s book (*) Categories 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 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■
