It should be possible to hide unexpected IO errors from validators to the users

[serby]

Because piton-validity it is impossible to stop unexpected errors from IO etc from showing to the user as a validation error. This needs addressing and possibly for piton-validity to be replaced.

Is this still an issue?

The title and description of this sound conflicting. If still valid, which is correct the title (should see errors) or description (shouldn't see errors)?

This is still an issue. I've fixed the title.

The validators need to show a default unexpected error message if there is a non-validator error returned or these errors need to be tracked and the application throw an error.
