Represents referencing a global variable.
$foo ^^^^
The name of the global variable, which is a ‘$` followed by an [identifier](github.com/ruby/prism/blob/main/docs/parsing_rules.md#identifier). Alternatively, it can be one of the special global variables designated by a symbol.
$foo # name `:$foo` $_Test # name `:$_Test`

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

:global_variable_read_node

Return a symbol representation of this node type. See ‘Node::type`.

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