Package pinata is a utility to beat data out of interface{}, []interface{} and map[string]interface{}.
Unlike other packages most methods do not return an error type. They become a no-op when the first error is found so the error can be checked after a series of operations instead of at each operation separately (inspired by https://blog.golang.org/errors-are-values). Special care is taken to return good errors so you can still find out where things went wrong.
