<p>Simple mode that tries to handle APL as well as it can.</p>

[64] Fix | Delete

<p>It attempts to label functions/operators based upon

[65] Fix | Delete

monadic/dyadic usage (but this is far from fully fleshed out).

[66] Fix | Delete

This means there are meaningful classnames so hover states can

[67] Fix | Delete

have popups etc.</p>
