Represents reading a local variable. Note that this requires that a local variable of the same name has already been written to in the same scope, otherwise it is parsed as a method call.
foo ^^^
The name of the local variable, which is an [identifier](github.com/ruby/prism/blob/main/docs/parsing_rules.md#identifiers).
x # name `:x` _Test # name `:_Test`
Note that this can also be an underscore followed by a number for the default block parameters.
_1 # name `:_1`
The number of visible scopes that should be searched to find the origin of this local variable.
foo = 1; foo # depth 0 bar = 2; tap { bar } # depth 1
The specific rules for calculating the depth may differ from individual Ruby implementations, as they are not specified by the language. For more information, see [the Prism documentation](github.com/ruby/prism/blob/main/docs/local_variable_depth.md).

def initialize(source, node_id, location, flags, name, depth)
@source = source
@node_id = node_id
@location = location
@flags = flags
@name = name
@depth = depth
end
Initialize a new LocalVariableReadNode node.

def self.type
:local_variable_read_node
end
Return a symbol representation of this node type. See ‘Node::type`.

def ===(other)
other.is_a?(LocalVariableReadNode) &&
(name === other.name) &&
(depth === other.depth)
end
Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.
