-Explanation: You can ❰merge❱ the alternatives of a union using a record with one
-handler per alternative, like this:
-
-
- ┌─────────────────────────────────────────────────────────────────────┐
- │ let union = < Left = +2 | Right : Bool > │
- │ in let handlers = { Left = Natural/even, Right = λ(x : Bool) → x } │
- │ in merge handlers union : Bool │
- └─────────────────────────────────────────────────────────────────────┘
-
-
-... as long as the input type of each handler function matches the type of the
-corresponding alternative:
-
-
- ┌───────────────────────────────────────────────────────────┐
- │ union : < Left : Natural | Right : Bool > │
- └───────────────────────────────────────────────────────────┘
- ⇧ ⇧
- These must match These must match
- ⇩ ⇩
- ┌───────────────────────────────────────────────────────────┐
- │ handlers : { Left : Natural → Bool, Right : Bool → Bool } │
- └───────────────────────────────────────────────────────────┘
-
-
-For example, the following expression is $_NOT valid:
-
-
- Invalid: Doesn't match the type of the ❰Right❱ alternative
- ⇩
- ┌──────────────────────────────────────────────────────────────────────┐
- │ let handlers = { Left = Natural/even | Right = λ(x : Text) → x } │
- │ in let union = < Left = +2 | Right : Bool > │
- │ in merge handlers union : Bool │
- └──────────────────────────────────────────────────────────────────────┘
-
-
-Your handler for the following alternative:
-
-↳ $txt0
-
-... needs to accept an input value of type:
-
-↳ $txt1
-
-... but actually accepts an input value of a different type:
-
-↳ $txt2
