Go

Use /// to hide verbose code but still allow the ability to execute it.

If you press y to copy (yank) this code block it will return the full snippet.

And, if you press ctrl+e it will run the program without error, even though what is being displayed is not a valid go program because we have commented out some boilerplate to focus on the important parts.
