- コマンドの解釈をしているみたい
- instance の中身

=>

@args=["new", "hello_app"],
@options={},

instance.invoke_command(command, trailing || []) でコマンド実行- 一応 invoke_command の中身

- send は 第一引数のメソッドを実行する name は
application
- step したら
Rails::Command::ApplicationCommand#perform へ飛んだ（なんで？
- instance は
Rails::Command::ApplicationCommand なので instance.application を実行...のはず
- pry で見ると 'instance.application' は確かにある
[1] pry(#<Thor::Command>)> instance.
