def_node_matcher :be_falsy?, "(send nil? :be_falsy ...)\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!
