- <p>Simple mode that tries to handle APL as well as it can.</p>
- <p>It attempts to label functions/operators based upon
- monadic/dyadic usage (but this is far from fully fleshed out).
- This means there are meaningful classnames so hover states can
- have popups etc.</p>

- <p><strong>MIME types defined:</strong> <code>text/apl</code> (APL code)</p>
