Whoops.  It is straightforward enough to add a 'for-each' function.
I'll see if I can do that right now.

Ugh.  copying ... bad.  Foreach, much better.  My only concern is that
I am not convinced that simply asking for all paramters is the right
thing to do for whatever it is that you are doing.  There are very few
realistic situations where knowing 'all' parameters is the right thing.
Most other cases require specialized knowledge of what the object really
is & does.
