Even in the fast fail case it would help if it told you which constraint failed. In the example from the readme it says the row failed validation, but not why.

Even in the fast fail case it would help if it told you which constraint failed. In the example from the readme it says the row failed validation, but not why. Would be nice if it said something like “items of `tags` must be type string, but integer was given”. Or even just that it was an invalid item type found in tags.
