It sounds good: "choose to print all the problems, rather than just one"
If so, it seems enough to only return a bool value to known whether success or fail, do not need the error details any more (since they are already been printed)

If we really want this patch (still only print the first error, and return the real error value), I should send patch v2 (also 'ret' is obsoleted)
