@rauschma FWIW you prob want one example without a close api.

In the C++ world there’s a term “RAII” (resource acquisition is initialization) and it refers to using explicit resource management to acquire resources. And even if something doesn’t need to be “closed” per se, you still use RAII to “clean up,” whatever that means for your resource. An example using explicit resource management is to create a disposable temporary file, use it during fn body, and delete it on dispose.
