class Prism::AliasGlobalVariableNode

^^^^^^^^^^^^^^^
alias $foo $bar
Represents the use of the ‘alias` keyword to alias a global variable.

def self.type

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

def ===(other)

comparing the value of locations. Locations are checked only for presence.
Implements case-equality for the node. This is effectively == but without

    (new_name === other.new_name) &&
    (old_name === other.old_name) &&
    (keyword_loc.nil? == other.keyword_loc.nil?)
