[History] An editor letter by Edsger Dijkstra, titled: "go to statements considered harmful" (march 1968). (dl.acm.org)

In this letter, Dijkstra talks about readability and maintainability in a time where those topics were rarely talked about (1968). This letter was one of the main causes why modern programmers don't have to trouble themselves with goto statements. Older languages like Java and C# still have a (discouraged) goto statement, because they (mindlessly) copied it from C, which (mindlessly) copied it from Assembly, but more modern languages like Swift and Kotlin don't even have a goto statement anymore.

Forget about goto, the latest version of C# introduced what's essentially comefrom.

Please don't link to medium articles. That page is terrible to visit.

Looks fine on Firefox on Android with uBlock Origin. 🤷‍♂️

I'm running exactly the same and it doesn't look fine on my end.

[–] [email protected] 1 points 7 months ago (1 children)

Huh. Maybe it's NoScript, then.

[–] [email protected] 2 points 7 months ago

Could be. I'm getting forced to make an account and such. That's why I hate medium.

To be fair, await is a bit more like comefrom, and it's been around for a few releases now.

async/await was introduced in version 4.5, released 2012. More than a few releases at this point!

How is await like comefrom, any more than threading is like comefrom? The variable context is preserved and you have no control over what is executed before the await returns.

What...? That is a terrible idea.

It's scary as fuck, yeah, but, to be fair, it's only intended to be used by code generators, and it's quite awkward to use outside of them.
