You "could" make it work by overloading foreach...  Not that I would
advocate that *g*.   But is that a requiredment to behave exactly like
tables?  He may want to add arithmetic tag methods and then they are
really different.  Using the get/settable method is just a way to get
a nice syntax to access fields.

A "next" and "tostring" method would be really nice though.
