title: With 'autoload' being deprecated, what should devs use in the meantime?
body: <p>Having read a couple weeks ago that <code>autoload</code> is <a href="https://bugs.ruby-lang.org/issues/5653" rel="nofollow noreferrer">officially deprecated</a>, Matz discourages use of it.  What is to replace it?  What should developers do instead?  I used it in some command-line gems to save unnecessary loading of libs that may never be used, as well as in JRuby to prevent the same for <code>.jar</code> files.</p>
