Hi all, I understand that once an ansible variable is set, it cannot be unset. I did find the [medium.com](http://medium.com) article below that explains a work around. Unfortunately, I do not understand some of the syntax. Specifically:  
“-bock: &debug”  
“-bock: \*debug”  
foo: !!null

Thanks for any help. Article I’m referring to is below.
