Overview

Represents the collection of multiple values of the right hand side of an assignment into a single value, for use in single assignment, e.g.:

lhs = a, b, c

The argument to this node is an Array. If it is length 0, returns nil. If it is length 1, returns the first element in the array. Otherwise, returns the array.

Class Method Summary

• .members ⇒ Array

  Return an array of strings containing the names of the node class’s members.
