Please forgive my #rstats ignorance, but where can I go to learn about what double-bang `!!` and triple-bang `!!!` notation mean in R? Is it an {rlang} thing? A tidyeval thing? A something-else thing? And where it is explained?
Example: a bit ways down this section, there's code that defines a list called `cards`, then later references that list as `!!!cards`.

I'm not sure exactly what's going on there.
@capbri @kellybodwin @jennybryan This is quotation to control when expressions (?) are evaluated.
@DataAngler @kellybodwin @jennybryan @etiennebacher Thanks so much everyone!(!!!)
@capbri @kellybodwin you've already gotten some great serious suggestions in the replies, so instead now I'm thinking ... somebody should make an animation illustrating what's going on when you use `!!` and `!!!` to inject arguments 😏
