doctest crashes after purrr update

[JZschache]

Hello,

after upgrading purrr fom 0.3.5 to 1.0.0, doctest crashes:

> devtools::document()

Error in `map()`:
ℹ In index: 1.
Caused by error in `purrr::modify()`:
! `.x` must be a vector, list, or data frame, not a call.
Run `rlang::last_error()` to see where the error occurred.

OK. I hope this is fixed in master, but I would very much appreciate if you could check!

Thank you for the quick response. It works now for me.
