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 a .rux 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 .rux file. To
  # fix this we have to intercept the cache lookup and force autoloading
  # the .rux file if one exists.
  cached_path = Bootsnap::LoadPathCache.load_path_cache.find(path)
  cached_rux_path = "#{cached_path.chomp('.rb')}.rux"
