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