rb_autoload_str may be safer by preventing premature GC. It can also be more efficient by passing a pre-frozen string that can be deduped using rb_fstring. Common autoload callers (e.g. rubygems, rdoc) already use string literals as the file argument. There seems to be no reason to expose rb_autoload_str to the public C API since autoload is not performance-critical. Applications may declare autoloads in Ruby code or via rb_funcall; so merely deprecate rb_autoload without exposing rb_autoload_str to new users.
