So there's yet another level of quirkery to this bullshit then, it seems. ๐Ÿ˜† Nice digging! ๐Ÿค

I also noticed that if you surround the curlies with parentheses, you get the same again:

> eval('{} + []')
0
> eval('({}) + []')
'[object Object]'

Yep, parentheses force {} to be interpreted as an expression rather than a block โ€” same reason why IIFEs have !function instead of just function.

/me goes back to get second folding chair.

I thought IIFE's usually looked like (function (...params) {})(...args). That's not the latest way? To be honest I never used them much, at least not after arrow functions arrived.
