Core.Match (morel 0.3.0 API)

java.lang.Object
- net.hydromatic.morel.ast.AstNode
- - net.hydromatic.morel.ast.Core.BaseNode
  - - net.hydromatic.morel.ast.Core.Match

Enclosing class:

Core
```
public static class Core.Match
extends Core.BaseNode
```
Match.
In AST, there are several places that can deconstruct values via patterns: fun, fn, let, case. But in Core, there is only Match, and Match only occurs within case. This makes the Core language a little more verbose than AST but a lot more uniform.
