Closures in Go

What are closures?

• Wikipedia mentions: "a closure is a technique for implementing lexically scoped name binding in a language with first-class functions."

What does that mean?

• We may write functions with access to the current scope, put the function in a variable, and pass it to a different part of the application that normally doesn't have access.

Why bother?

• Create methods that have asynchronous operation.
• Send local objects to remote places. Examples are e.g. database handles or logging instances.

Repository examples are in pkg/

Real world examples

• Naiserator is a Kubernetes operator written by NAV. It manages Kubernetes resources using a create, update or delete mechanism implemented with closures.
