Despite being formally dual to monads, they don’t seem to be “all the rave” like monads are. Just because you get ‘em by just reversing some arrows doesn’t mean that comonads aren’t independently interesting!

Monads look pretty different in math vs in programming… what exactly are they? (Don’t say they’re just monoids in the category of endofunctors,… I mean it.)

A programming language for multilingual grammar applications

Curry is a declarative multi-paradigm programming language which combines in a seamless way features from functional programming (nested expressions, higher-order functions, strong typing, lazy evaluation) and logic programming (non-determinism, built-in search, free variables, partial data structures). Compared to the single programming paradigms, Curry provides additional features, like optimal evaluation for logic-oriented computations and flexible, non-deterministic pattern matching with user-defined functions.
