[fw-general] Subclassing Zend_Db_Table_Row

[Taylor Barstow]

Hi,

I'd like to add support for subclassing Zend_Db_Table_Row.  Is this 
already in the works or is this a worthwhile thing for me to work on?  
It would probably be a pretty small patch.  My goals would be:

1. To add a couple of static methods to allow the developer to choose an 
application wide row subclass (much like Zend::initRegistry())
2. To (perhaps in a second iteration) add support for subclassing on the 
fly; for example, I might want to set a custom subclass for the rows 
generated by each of my table modules so that I can add domain methods.

Any thoughts? 

My initial reason for doing this is so that I can implement 
IteratorAggregate so that I can iterate over the row's properties.  
toArray() is not sufficient because it returns the under_score version 
of the column names, rather than the camelCaps version, which is what 
exterior objects should be working with.  But long term, I think 
subclassing would be useful for other reasons as well.
