Scoped Implicit Lifetimes

All things considered, our experience in Scala Native has shown that resource management in Scala is way harder than it should be. This gist presents a simple design pattern that makes it resource management absolutely hassle-free: scoped implicit lifetimes.

The main idea behind it is to encode resource lifetimes through a concept of an implicit scope. Scopes are necessary to acquire resources. They are responsible for disposal of the resources once the evaluation exits the
