        # @return [Reek::AST::Node] the condition that is associated with a conditional node.

        #
        #     if charlie(bravo) then delta end
        #
        #   would be parsed into this AST:

        #
        #   so in this case we would return this

        #     s(:send, nil, :charlie,
        #       s(:lvar, :bravo))
