While it's convenient to have CDBI magically use relationships to 
inflate foreign keys into other CDBI objects, I question the wisdom of 
piggybacking other forms of inflation upon the same mechanism.  I 
question even the wisdom of inflating CDBI objects using the current 
syntax, since many many people use blah_id as their foreign kay, and 
calling $obj->blah_id() to get the $blah object is nonsesnsical (and the 
workarounds have problems, too).

It seems to me that the solution is seperating the relationship syntax 
from the inflation/conversion/mapping/whatever syntax.  One set of 
methods to define relationships (which are *table relationships*, not 
the relationship between a datetime value and a datetime object) and 
another set of methods to inflate/deflate column values.
