Represents the use of the ‘^` operator for pinning a variable in a pattern matching expression.
foo in ^bar

Initialize a new PinnedVariableNode node.

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

other.is_a?(PinnedVariableNode) &&

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