Prof. André C. P. L. F. de Carvalho at CEPID-CeMEAI (Grants 2013/07375-0 – 2019/01735-0).HistoryThe novel ideias presented here are a result of a years-long
process of drafts, thinking, trial/error and rewrittings from scratch in several languages from Delphi, passing through Haskell, Java and Scala to Python - including frustration with well stablished libraries at the time. The fundamental concepts were lightly borrowed from basic category theory concepts like algebraic data structures that permeate many recent tendencies, e.g., in programming language design.For more details, refer tohttps://github.com/davips/kururu
