Code
  count(df1, x, name = 1)
Condition
  Error in `dplyr::tally()`:
  ! `name` must be a single string, not the number 1.

Code
  count(df1, x, name = letters)
Condition
  Error in `dplyr::tally()`:
  ! `name` must be a single string, not a character vector.

can only explicitly chain together multiple tallies
