(First, I made a similiar post already but it seems to have 
not made it to through the gates of the monastery.  I apologize
if it shows up twice.)

You make a very good point about the dangers here, and I 
will certainly implement your ideas.  However, I am a little
stumped how the constructors you listed would prevent the 
problem.

Can you elaborate?

For instance, how does:

 my $self= bless {%$hashRef}, $class;

protect the objects from being changed in the way you describe.

One thing I did was make %_permitted be a hash that is created
from the table data as well, so only those columns in the table
can be in the object and not anything extra, so that you if you
add to that hash randomly the hash will have the value but the
object will not allow it.  So, if it is not in the _permitted hash
then it is not part of the object.  Does that address the issue
in part, or did I misunderstand?
