Random Scala Tip #568: Beware of Leaking Iterators - Daniel Beskin
Beware of leaking `Iterator` instances outside the scope you initialized it in.
Don't get me wrong, Amazon working on its own Linux-based OS is a good thing, but HTML-based applications instead of native ones? Brr...
I would really like to maintain more OSS libraries, but to be honest, most of the time I'm just fixing publish pipelines 😡
It's a paradox, but for me, it's much harder to reason about a program written in direct style. But hey, Ox turned into a production-ready library, so it's time to consider it a viable alternative! 🎉 #scala
