Could anyone explain to me what are the differences between data/type constructors and functions? Haskell mix 开发者_开发百科them and give us a universal interface (all looks like functions, in partic
Update: I realize that I put the question very badly. Here\'s a second run. Consider the following function:
I read this term a lot in blogs about haskell and functional programming (specially in sigfpe\'s blog) but I don\'t have a clue about what it means. I get away with not knowing it most of the times, b
Fold (aka reduce) is considered a very important higher order function. Map can be expressed in开发者_运维百科 terms of fold (see here). But it sounds more academical than practical to me. A typical u
Which of the three (if any (please provide an alternative)) would be used to add elements to a list of items?
