In the landscape of modern programming languages, automatic garbage collection and RAII (Resource Acquisition Is Initialization) have become the norm. The Odin programming language, however, takes a distinct path. It embraces simplicity, data-orientation, and explicit control. One of the key functions that exemplifies this philosophy is rqt-close (often accessed via the core:sys/windows or similar platform-specific bindings, or as part of a custom runtime). h := CreateFile("data

In Odin, every open deserves a close, every create a destroy. Your future self (and your operating system) will thank you.
