( #3333=superdoc: print w/replies, xml ) Need Help??
A personal nit here - I've played with tieing to provide hard encapsulation and found that it slowed down accessing the object by at least 50%. I wasn't limiting myself to just validation, but tie creates a lot of overhead. Frankly, I don't see the sugary benefits here outweighing the large performance hit. I do a lot of CGI work where SLA's have to be met and hardware simply will not be increased this year. Performance, while not the first priority, simply cannot be the last priority. I use OO for maintainability. I don't want it to also become a liability.
