I don't see why this went on so long. so you can have variable variables, and by using curly braces you can do inline evaluation of a expression.

It's no different from just evaluating any expression, no matter how complex, that returns a string, storing it in a variable then sticking a $ sign in front of it.

This is not a rabbit hole. It's just a bucket someone threw up into and then posted onto reddit.
