> The {{abandon_ship()}} function catches errors that occur because of unsupported functions/arguments and issues warnings in place of the of errors. These warnings do not use the same messages as the errors.
> There are many dplyr tests that use {{expect_warning()}} to effectively check that an error occurred before it was converted to a warning. These tests do not assert the expected error message, because that message is lost in the conversion to a warning.
> Consider ways to improve these tests to enable them to assert the expected error messages.
> Alternatively, consider:
> * Whether we intend to keep {{abandon_ship()}} working as it does even after dplyr support in the package becomes more comprehensive
> * Whether we should modify {{abandon_ship()}} to incorporate the original error message into the warning it gives instead of throwing a generic and likely less helpful warning message
