def_node_matcher :be_truthy?, "(send nil? :be_truthy ...)\n"

#on_send(node) ⇒ Object Also known as: on_csend

Called on every send node (method call) while walking the AST. TODO: remove this method if inspecting send nodes is unneeded for your cop. By default, this is aliased to on_csend as well to handle method calls with safe navigation, remove the alias if this is unnecessary. If kept, ensure your tests cover safe navigation as well!
