Ah, I see!  (I've always used different names when needing to do that
sort of thing).

For a single form submission, maybe, but not for setting the "checked"
attribute correctly in displayed forms.  I just tried the form you
suggested above, and it only displays the checkboxes correctly if
there is no more than one checkbox selected (if more than one was
selected, they all end up unchecked).

The code in prepare_attrs() has expressions like '$value eq $original'
and '$default eq $original' which (unless I'm missing something else
again :-), don't allow for the possibility of more than one checkbox
being selected.

I'll have to rethink my proposal :-).  Thanks for your example.
