Class PushScope

java.lang.Object

hlt.language.design.instructions.Instruction

hlt.language.design.instructions.PushScope

All Implemented Interfaces:

PushObject

Direct Known Subclasses:

PushClosure

public class PushScope
extends Instruction
implements PushObject

A PushScope instruction is to a PushClosure instruction what a Scope expression is to an Abstraction expression. In other words, it is a PushClosure that does not need any frame machinery.
