So just as an alternative for class hierarchies? I mean good people already balance that by having a preference for composition.
- munchler 5mo agoSimple example: type Expr = | Primitive of int | Addition of (Expr * Expr) | Subtraction of (Expr * Expr) | Negation of Expr
- Quarrelsome 5mo agoIsn't that just Func<int> ?
- afdbcreid 5mo agoReally not. You can, of course, having instead a delegate to evaluate the expression. But then that's all you can do. You can't pretty-print it, for example, or optimize it, or whatever.

- LeFantome 5mo ago“Compoision”. A typo I know but it would be a word describing what goes wrong with class hierarchies.
