pleeeeease stop referring to hypothetical software developers as "he" by default. if you quickly add "or she" afterwards you're still on my shitlist. we have a perfectly serviceable generic singular pronoun, "they" - use it
@chr I'm also a fan of defaulting to “she” for traditionally male-dominated fields.
It annoys exactly the right people, and does a small amount of good, while not having even the potential of the stupid grammar dead end distractions.
Of course, “they” is perfectly acceptable also.
Consider this a friendly, local pub. Make yourself at home, bring your friends, have a good time! Meet new people, have a laugh, enjoy the ambience, and the Oxford commas.
