The context for my absurd rant above is that [I was just complaining](https://fosstodon.org/@yjunechoe/112039945400602627) about how I think `args()` is a rather poorly designed function.

One thing I neglected to mention in this blog post is that there are other ways to extract a function's arguments. One of them is `formals()`:^[But note that it has a [special behavior](https://adv-r.hadley.nz/functions.html?q=formals#primitive-functions) of returning `NULL` for primitive functions (written in C) that clearly have user-facing arguments on the R side. See also `formalArgs()`, for a shortcut to `names(formals())`]
