`nil` YARD annotation not recognized in arrays, hashes?

[thomthom]

Is nil not always recognized by steep?

module Example

  # @return [nil]
  def self.hello
  end

  # @return [Array<Integer, nil>]
  def self.world
  end

end

Shouldn't nil always be resolved? The Boolean YARD meta type appear to have no problems.

module Example

  # @return [Boolean]
  def self.foo
  end

  # @return [Array<Integer, Boolean>]
  def self.bar
  end

end

Hi @thomthom,

It looks like the issue is something related to sord. Could you ask it with the developer of sord? Let me know if there is anything Steep/RBS can help. https://github.com/AaronC81/sord
