> `function _fizzbuzz () {`

I find that extra keyword distracting, when [POSIX.2 doesn't require it][1] and some folks going so far as to say to [actively avoid it][2]

Is there some good reason for it, or people are just used to a programming language requiring `fun` before a declaration, so it's programmer muscle memory?

Simple keywords for definitions can make grepping for stuff much easier. Given that shell allows other forms, it isn't that helpful in practice. I still use it because my eyes find start-of-definition faster with common patterns that are not just special-chars. YMMV.

Edit: I usually don't care for portability, and just use bash. Shell is so ugly already, I refuse to write my personal stuff in portability hell mode. Rather level up my Civilization skills instead.
