funs vs lists on scoped verbs

[dan-reznik]

per dplyr 0.8.x the "funs()" paramenter will be soft deprecated in favor of lists, so you may want, for longevity purposes, propose the new format on the *_{at,if,all} verbs

fns <- list(
  centered = mean,                # Function object
  scaled = ~ . - mean(.) / sd(.)  # Purrr-style lambda
)
mutate_if(iris, is.numeric, fns)
