[Solar-talk] Solar_Sql_Model to DataMapper/Record/Collection

[Ian Szewczyk]

Do the offset methods need to be final? I addressed this in an earlier
posting but I think you should optionally be able to access the $_data
in a collection object without going through record objects (in a
manner similar to accessing normally, so if you have related stuff
loaded you wouldn't need to remember to access the existing relation
data with that double underscore, etc). It may be possible to custom
rig something through those offset methods.
