什么对象/进程拾取新创建的 Specification 运行时的对象 gem build 反对典型的 gemspec 文件
例如，假设我们有 mynewgem.gemspec 内容如下:

Gem::Specification.new do |s|
  s.name = "mynewgem"
  s.version = "0.0.1"
  s.summary = "here is a summary"
  s.description = "here is a desc"
  s.authors = ["Full Name"]
  s.email = "myname@mydomain.net"
  s.files = Dir.glob("lib/**/*", File::FNM_DOTMATCH)
  s.homepage = "https://rubygems.org/gems/mynewgem"
  s.license = "My License"

  s.add_dependency "this-dependency", "~> 1.2.3"
  s.add_dependency "that-dependency", "~> 4.5.6"
end

什么类/方法正在引用新创建的 Gem::Specification 反对吗？很明显，它不是直接赋给变量的 mynewgem.gemspec . 看到这个新对象的东西实际上是如何看到/引用它的？
