Represents writing to a class variable.
@@foo = 1 ^^^^^^^^^
The name of the class variable, which is a ‘@@` followed by an [identifier](github.com/ruby/prism/blob/main/docs/parsing_rules.md#identifiers).
@@abc = 123 # name `@@abc` @@_test = :test # name `@@_test`
The value to write to the class variable. This can be any [non-void expression](github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).
@@foo = :bar
^^^^
@@_xyz = 123

Initialize a new ClassVariableWriteNode node.

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

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