There is already the _autoload function, that works with the drawback that
you need to give the number of macros:

 DESCRIPTION
   The `_autoload' function is like the `autoload' function except that
   it takes `n' pairs of function name (`fun') / filename (`fn') pairs.
   For example,

           _autoload ("fun_a", "file_a", "fun_b", "file_b", 2);


The above could be even easier if you stick to the file-last convention:

%!% \usage{Void autoloads(String fun, [String fun[, ...]], String file)}
define autoloads()
{
   variable file = (), fun;
   loop (_NARGS-1)
   {
      fun = ();
      autoload (fun, file);
   }
}


However, when trying _autoload in my make_ini skript, I got problems:

% the idea to use _autoload and _add_completion did not work:
% a file with 12 global functions triggered a "line len too long" error

Question: how long can a line be, before the "line len too long" error is
triggered?
