Ask HN: What's a small language feature you've grown to love?

For me it's definitely Go's time.Duration type. Having a simple and standard way to handle timespans has been really helpful for my past few projects, and the parsing format has been great for command-line interfaces. No more external libraries or rolling my own, I can just type "1m2s" and Go gets it.

What about you?

Elm's package management. In elm if you change your API you must change the version of your package following Semantic versioning.

1.1.2 Major.minor.patch.

Or better: Break.feature.fix

And that comes from the language and package manager.
