+title: Go's iterators suit the moronic language
+date: 2025-06-07
+---
+
+Just had to deal with Go iterators and I can say that they fit the language
+well.
+
+They're push iterators. It's as if you're just appending items to an array.
+Actually much easier to explain.
+
+They compile down to nonlocal returns to try to keep it fast, but of course it's
+still slower than a state machine. The case for every single thing in Go really.
+
+And when you know slightly more than a single lick of programming, the design
+and implementation of them looks very obviously moronic and catered to
+beginners.
+
+Some people were arguing that this approach makes it more "functional" but
+that's very far from the truth. Push iterators are very imperative, pull
+iterators (`Iterator::next`, which returns `Option<T>`) are actual functional,
+correct and fast way to do it.
