public final class ResolveVariableNode
extends ExpressionNode

Resolves a variable name, for example `foo` in `x = foo`.

A variable name can refer to any of the following: - a (potentially `local`) property in the lexical scope - a method or lambda parameter in the lexical scope - a base module property - a property accessible through `this`

This node's task is to make a one-time decision between these alternatives for the call site it represents.
