  [;1m-spec delete_module(Module) -> true | undefined when Module :: module().[0m

  Makes the current code for [;;4mModule[0m become old code and deletes
  all references for this module from the export table. Returns [;;4m[0m
  [;;4mundefined[0m if the module does not exist, otherwise [;;4mtrue[0m.

  Warning:
    This BIF is intended for the code server (see [;;4mcode(3)[0m) and
    is not to be used elsewhere.

  Failure: [;;4mbadarg[0m if there already is an old version of [;;4mModule[0m.
