prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  export-default
   +--__snapshots__
   +--escaped
   |   `--__snapshots__
   `--export-default-from
       `--__snapshots__
  ```
  
  Convert this description:
  
  babel-runtime-corejs2 is a root directory that assembles 3 subdirectories: core-js, helpers and regenerator.
  At the top level, Inside 'core-js', you'll find it is an empty container.
  In the root directory, 'helpers' encompasses 1 nested folders: esm.
  In nested path 'helpers / esm', 'esm' holds no subdirectories at the moment.
  At the main level, 'regenerator' sits empty.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
