The title made me think of "You Could Have Invented Monads (And Maybe You Already Have)" (http://blog.sigfpe.com/2006/08/you-could-have-invented-monads-and.html http://blog.sigfpe.com/2006/08/you-could-have-invented-monad...), which according to one of the comments in http://blog.ezyang.com/2012/02/anatomy-of-you-could-have-invented/ http://blog.ezyang.com/2012/02/anatomy-of-you-could-have-inv... was inspired by this article
- dirkt 8y agoThough I have to say that [chain complexes](https://en.wikipedia.org/wiki/Chain_complex https://en.wikipedia.org/wiki/Chain_complex) and their [homotopy](https://en.wikipedia.org/wiki/Homotopy_category_of_chain_complexes https://en.wikipedia.org/wiki/Homotopy_category_of_chain_com...) are somewhat more difficult than the structure you need to understand monads. You can even explain monads purely in programming terms, without reference to category theory.
