# File lib/prism/node.rb, line 14334 def ===(other) other.is_a?(PinnedVariableNode) && (variable === other.variable) && (operator_loc.nil? == other.operator_loc.nil?) end
Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.
