I use a 'ghost' class for this: a general purpose data holder that 
mimics the behaviour of a designated cdbi class in simple but useful 
ways and has make() and find_or_make methods() that turn it into a real 
cdbi object. There's a version of this approach in 
Class::DBI::Factory::Ghost, which could easily have its reliance on the 
factory removed. I normally use it to hold either the precursor of an 
object to be created or the echo of an object just deleted, so that 
it's easy to display them on templates.

However, after many previous discussions of this topic I think it's 
fair to say that most people regard this approach as evidence of Poor 
Structure and Bad Thinking. see eg:
