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.
