def autoload(const, path)
  # Bootsnap monkeypatches Module.autoload in order to leverage its load
  # path cache, which effectively converts a relative path into an absolute
  # one without incurring the cost of searching the load path.
  # Unfortunately, if an unprocessed file has already been transpiled, the
  # cache seems to always return the corresponding .rb file. Bootsnap's
  # autoload patch passes the .rb file to Ruby's original autoload,
  # effectively wiping out the previous autoload that pointed to the
  # unprocessed file. To fix this we have to intercept the cache lookup and
  # force autoloading the unprocessed file if one exists.
  cached_path = Bootsnap::LoadPathCache.load_path_cache.find(path)

  if (unprocessed_path = Onload.unprocessed_file_for(cached_path))
    return super(const, unprocessed_path)
