The short answer is that I didn't know about its existence. Thank you so
much for directing my attention to it.

The longer answer is that while this does indeed solve the problem at hand
(and I've already pushed it to gnu-apl-mode), there may be more complicated
cases where an answer to the original question may be needed.

So in the interest of satisfying my own curiosity, is there a way to
determine the height of a given string?
