net.hydromatic.morel.ast.Core.Id

All Implemented Interfaces:

Comparable<Core.Id>

Enclosing class:

Core

public static class Core.Id
extends Core.Exp
implements Comparable<Core.Id>

Reference to a variable.

While Ast.Id is widely used, and means an occurrence of a name in the parse tree, Id is much narrower: it means a reference to a value. What would be an Id in Ast is often a String in Core; for example, compare Ast.Con0Pat.tyCon with Core.Con0Pat.tyCon.
