First, sorry for the lengthy post. Basically, my question is this: I\'m trying to reproduce the following F# discriminated union type in C#:
I\'m getting an error I don\'t quite understand: AnotherModule.hs:6:38: `something\' is not a (visible) field of constructor `M.SomeType\'
When dealing with sizeable algebraic data types in Haskell, there is a particular recursive traversal not captured by folding over the data type. For instance, suppose I have a simple data type repres
I am using C++ to code some complicated FFT algorithm, so I need to implement such algebraic structures as quaternions and Hamilton-Eisenstein codes. Algorithm works with 2D array of that structures.
In Haskell, is it possible to write a function with a signature that can accept two different (althoug开发者_Python百科h similar) data types, and operate differently depending on what type is passed i
While commenting on new features in ghci I wished that ghci had the ability to declare type declaration and declaring new ADT types, someone informed that it was indeed possible, and after searching I
I recently getting to know about functional programming (in Haskell and Scala). It\'s capabilities and elegance is quite charming.
How can I find the actual amount of memory required to store a value of some data type in Haskell (mostly with GHC)? Is it possible to evaluate it at runtime (e.g. in GHCi) or i开发者_开发百科s it pos
As it currently stands, this question is not a good fit for our Q&A format. We expect answers to be supported by facts, references,or expertise, but this question will likely solicit debate, a
Imagine I have a recursive algebraic data type like this (Haskell syntax): data Expr = Zero One Add Expr Expr
