Does anyone have a good resource on this family of languages or otherwise on any of them individually? Every time I&#x27;ve run across references to K&#x2F;Q I&#x27;ve poked around a bit and it feels like they kind of exist as linguistic curiosities in some vacuum with a vaguely unexplained creation myth about a man named Whitney.<p>Edit: found this paper which appears to be around the birth of array languages by the developer of APL.
