Isn't this the exact same number of keystrokes? 'Shift-3 p' versus 'Shift-9 p' on my keyboard.

It has to do with the fact that air pollution has massively decreased, but cars still kill a lot of people. That's a considered and substantive point, I reckon. I wrote it because in my experience a "balance" between modes

Because rail infra scales really well, bus infra scales well, and bike infra scales well -- while car infra scales disastrously.

This looks like the other completely normal, idiomatic Clojure programs I've seen which manipulate a StringBuilder. And as Clojurians go I'm far to the succinctness/concision-preferring end of the spectrum. I'm curious t

No: a Turkish keyboard has separate i/İ and ı/I keys, and Türkish-writing users with an American/international keyboard use a keyboard layout with modifier keys so that the i/I key can be altered to ı/İ. (I do the l

He wasn't writing corporate CRUD apps, he was working on systems like radio broadcasting, voting machines, and Datomic, which involve significant concurrency challenges.

Datomic doesn't scale? Quick, tell the largest bank in South America, they must already be collapsing under the weight of all those transactions!

Interop to APL from Clojure is completely wild and masochistic indeed. Hadn't seen this, thanks

>should functions return (value, error), or (error, value)? a benefit of using maps with error keys :D semantic rather than positional destructuring. also avoids that needlessly obfuscatory Left and Right terminology for Either monads

The "error maps" approach from the article doesn't have Go's compiler enforcement, but shares many attributes including the "being explicit about how to handle an error" aspect you mention.

Throwing ex-info is conspicuously missing from your list of examples. >If everything is idiomatic, is anything idiomatic? Welcome to lisp! We like it here.

I considered "Idiomatic error handling in Clojure" and decided to err on the side of concision. Tbh the latter interpretation was not one that occurred to me. Curious what you would put in such an article.

People's use of spec varies widely. My take is that error maps are for internal work. Contracts are for what passes over some sort of system boundary, so it seems feasible to just...not spec the monadic aspect? Personally I haven'

:tried is new to me, thanks for the tip! In the context where I've used this the most the entire map was the payload/parameter so it didn't make sense there, but I see where that could be useful. I like having a :type key - f

Beg buttons are the worst. Traffic engineers who design them into any but the most remote intersections should be ashamed of themselves. One more piece of obscene car culture and dependence.
