errors for bad inputs

Code
  vars_pull(letters, character())
Condition
  Error:
  ! `character()` must select exactly one column.
Code
  vars_pull(letters, c("a", "b"))
Condition
  Error:
  ! `c("a", "b")` must select exactly one column.
Code
  vars_pull(letters, !!c("a", "b"))
Condition
  Error:
  ! `!!c("a", "b")` must select exactly one column.
Code
  vars_pull(letters, aa)
Condition
  Error:
  ! object 'aa' not found
Code
  vars_pull(letters, 0)
Condition
  Error:
  ! Can't extract column with `0`.
  x Subscript `0` must be a positive location, not 0.
Code
  vars_pull(letters, 100)
Condition
  Error:
  ! Can't extract columns past the end.
  i Location 100 doesn't exist.
  i There are only 26 columns.
Code
  vars_pull(letters, -100)
Condition
  Error:
  ! Can't extract columns past the end.
  i Location 100 doesn't exist.
  i There are only 26 columns.
Code
  vars_pull(letters, -Inf)
Condition
  Error:
  ! Can't extract column with `-Inf`.
  x Can't convert from `-Inf` <double> to <integer> due to loss of precision.
Code
  vars_pull(letters, TRUE)
Condition
  Error:
  ! Can't extract column with `TRUE`.
  x `TRUE` must be numeric or character, not `TRUE`.
Code
  vars_pull(letters, NA)
Condition
  Error:
  ! Can't extract column with `NA`.
  x Subscript `NA` must be a location, not an integer `NA`.
Code
  vars_pull(letters, na_int)
Condition
  Error:
  ! Can't extract column with `na_int`.
  x Subscript `na_int` must be a location, not an integer `NA`.
Code
  vars_pull(letters, "foo")
Condition
  Error:
  ! Can't extract columns that don't exist.
  x Column `foo` doesn't exist.

gives informative error if quosure is missing

Code
  f()
Condition
  Error in `f()`:
  ! `var` is absent but must be supplied.

vars_pull() are base errors

Code
  vars_pull(letters, foobar)
Condition <rlang_error>
  Error:
  ! object 'foobar' not found

vars_pull() errors mention correct calls

Code
  vars_pull(letters, f())
Condition <rlang_error>
  Error in `f()`:
  ! foo

vars_pull() produces correct backtraces

Code
  print(expect_error(vars_pull(letters, f(base = TRUE))))
Output
  <error/rlang_error>
  Error:
  i In argument: `f(base = TRUE)`.
  Caused by error in `h()`:
  ! foo
