Yes, but since the helpers: validation_errors() and form_error()
and methods: form_validation::error_string() and form_validation::error()
all return strings, I thought it would be generally assumed that form_validation::errors() would too. So I just thought it might be good to clarify in the name so its obvious, like they do with $db::result() and $db::result_array().

Now that I think of it, maybe you should create the matching helper in form_helper.php as well? Or even just even add a parameter to validation_errors('array' || 'string'[default])
