 #' Block usage of return() in magrittr pipelines

 #' [return()] inside a magrittr pipeline does not actually execute `return()`
-#'   like you'd expect: `\(x) { x %>% return(); FALSE }` will return `FALSE`!
-#'   It will technically work "as expected" if this is the final statement
-#'   in the function body, but such usage is misleading. Instead, assign
-#'   the pipe outcome to a variable and return that.
