I wanted to write an extension-method that would work on dictionaries whose values were some sort of sequence. Unfortunately, the compiler can\'t seem to infer the generic arguments from my usage of t
Problem Summary At the moment when using f# I must explicitly coerce a value to the parent type of its type in order to get pattern matching expressions to type check correctly.I would ideally like a
I\'ve been thinking about how type inference works in the following OCaml program: let rec f x = (g x) + 5
Let\'s consider the following function: def printPfType[T](pf:PartialFunction[T, _])(implicit m:Manifest[T]) = {
Reading Disadvantages of Scala type system versus Haskell?, I have to开发者_运维技巧 ask: what is it, specifically, that makes Haskell\'s type system more powerful than other languages\' type systems
The C# language specification describes type inference in Section §7.5.2. There is a detail in it that I don’t understand. Consider the following case:
I\'m looking for information about the well-known Damas-Hindley-Milner algorithm to do type inference for functional languages, especially information about implementation.
I\'m trying to write a method in F# that returns a new instance of a generic type based upon the type of a value passed into the method. In FSI:
List(\"This\",\"is\",\"Scala\").foreach(a => print(a+\" \")) compiles fine, but List(\"This\",\"is\",\"Scala\").foreach(print(_+\" \"))
Given the following code: type MyType() = static member processString (_string:string) = _string.Substring(0, 1)
