That's three times the reason not to use it!

Whether its protected or private, you reached for a shotgun when bug spray 
will do.

I'm not willing to comment on the naming conventions, but if its 
undocumented its undocumented and can change at any time.  Without a 
documented API you override at your own risk.

CDBI and Ima::DBI have a "special" relationship that's probably illegal in 
most US states.  They're maintained by the same author and often released at 
the same time.  Therefore, its not exactly the model for encapsulation.

I myself am trying to eliminate such coupling from my own modules.  I figure 
whatever guts I find myself poking at will be useful to someone else.  I've 
mostly torn Test::More and Test::Builder's unseemly embrace apart.
