Lint/NestedMethodDefinition false alarm on the @ presence

[yegor256]

I'm doing this:

class F
  def foo
    @x = Object.new
    def @x.bar(_t)
      true
    end
  end
end

Rubocop 1.64.0 complains:

a.rb:4:5: W: Lint/NestedMethodDefinition: Method definitions must not be nested. Use lambda instead.
    def @x.bar(_t) ...
    ^^^^^^^^^^^^^^

Looks like a bug.
