Coroutines for Go

Coroutines are a powerful concept in programming that allow for concurrent execution of functions. In this article, the author explores the need for a coroutine package in the Go programming language and what it would look like.

Traditionally, function calls in programming are sequential - one function runs at a time while its callers wait. Coroutines, on the other hand, run concurrently on different stacks, allowing for more efficient and flexible execution.

To illustrate the concept, the author uses Lua as an example. They demonstrate how coroutines can be used to compare two binary trees and yield each value for comparison. The code snippet showcases how coroutines can be created and resumed to achieve this.

The author also mentions generators in Python, which are similar to coroutines but have some differences. They highlight that direct translations from Lua to Python may not work as expected due to these differences.

Overall, this article provides insights into the concept of coroutines and their potential benefits in the Go programming language. It serves as a valuable resource for developers looking to understand and implement coroutines in their projects.
