It's so curious to me that functional disciples wear this as a badge of honor. In nearly all other facets of software development, we get badgered that it's better to produce code your entire team understands (code is read more often than written and all that) than code which only makes sense to you. If I ran around talking up the zen of single letter variables, my team would shoo me out of the room, and almost nobody on HN would applaud me for it. But for some reason, functional programming tends to get a pass, despite it just not clicking for a large swath of team mates.
