I was experimenting with type families yesterday and ran into an obstacle with the following code: {-# LANGUAGE TypeFamilies #-}
Does Curry have the ability to show or pretty print data types inside the REPL (using PAKCS or MCC)? In Haskell, this functionality is impemented using the type class Show. Howe开发者_运维知识库ver, n
I\'ve come acro开发者_StackOverflowss references to Haskell\'s Data.Typeable, but it\'s not clear to me why I would want to use it in my code.
I have a scenario that involves type classes and I\'开发者_如何学JAVAm not quite sure how to go about solving it.
I\'m new to D, and I\'m looking for a good way to program with Haskell-like type classes e.g. Functors, Monoids, etc. in D.
Given a function s开发者_开发技巧ignature like this (using the riak package): put :: (Storable a, Resolvable a, ToJSON a, FromJSON a) => Connection -> a -> IO ()
how can i group getX and putX in a class instance ? the code below is an answer for this post Class set method in Haskell using State-Monad
I have a (fairly) legitimate case where there are two type instance implementations, and I want to specify a default one. After noting that doing modular arithmetic with Int types resulted in lots of
I didn\'t expect the following code to work: foo :: (Num a) => a -> a foo x = x + x main = do print (foo (read \"7\"))
I write a library with Java interfaces resembling Haskell type classes, and abstract classes implementing all \"derivable\" methods (e.g. Monad.join can be written using >>= and return). This 开
