The documentation reads:
regexp
Regular expression to test against.
- A character vector giving a regular expression that must match the error message.

# test fails because of an error in expect_error():
# Error in `expect_error(object = f("bar"), regexp = c("foo", "bar"))`: `regexp` must be a single string, `NA`, or `NULL`, not a character vector.Is it intended for expect_error() to work with a regexp vector of patterns or should one always use a single pattern?
