Anton Zhiyanov explores the design decisions behind Go's slices.Backward iterator through a thought experiment, starting from naive implementations and evolving toward the final generics-based iterator signature. The article illustrates why Go's standard library chose complex generic iterator patterns over simpler alternatives like returning copies or closures.
Background
Go 1.23 introduced native iterator support and a new slices package with generic utility functions. This article is part of Anton Zhiyanov's technical blog exploring Go language design decisions.
