One of these days I want to give a compiler talk called "name lookup is the absolute worst" that's just 100 slides of screaming goat memes.

As a counter-point, what language(s) would you say have "good" name lookup rules, where "good" ?= easy and convenient for the programmer as well as the implementer?

Possibly Forth. Or APL or something. Combinatory forms rather than binding forms.

I even made a thing for this, but it's slowww github.com/brendanzab/mon - was thinking of going nominal and using visitors like in Visitors Unchained… that way I can fuse traversals together… but apparently you pay for it in other ways. 😭

Eelco Visser's scope graphs are also kinda neat, but I've not studied them too closely yet! eelcovisser.org
