     enum data-structures

    Haxe's enumeration types are algebraic data types. Their primary use is for describing data structures.‥

     enum pattern-matching functional-programming

    As already established Haxe enums are a form of algebraic data types. In fact, they may even serve as so called generalized algebraic data types - GADTs for short. While for an ordinary enum every constructor yields the same type, with an GADT each constructor may yield a different type. ‥

     enum expression-macro

    The following macro function returns an array of all possible values of a given @:enum abstract type. Since it's not possible in runtime (because abstracts doesn't exist there), we need to use a macro for that.‥

     enum pattern-matching expression-macro

    Sometimes we have an instance of enum that is of known constructor (or we only accept that constructor) and we want to extract values from that instance. Normally, to do this, we have to use pattern matching (switch), however it's quite verbose, so we can instead use this macro static extension method that will generate switch for us.‥

     enum abstract-type pattern-matching type-parameter type-parameter-constraint

    Sometimes you find yourself in the need of passing different types to the same parameter of a function. While there isn't a built-in way of doing this in Haxe, thanks to its flexible type system, we can solve this problem. We will explore two ways to achieve this.‥
