Represents writing to a class variable.
@@foo = 1 ^^^^^^^^^
The name of the class variable, which is a @@ followed by an identifier.
@@abc = 123 # name `@@abc` @@_test = :test # name `@@_test`
The value to write to the class variable. This can be any non-void expression.
@@foo = :bar
^^^^
@@_xyz = 123

Initialize a new ClassVariableWriteNode node.

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

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