What I'm trying to do here is avoid using <dtml-in, since in order for it to
put the object in the namespace it has to iterate over all of them (there
could be any number).

All I have at the beginning is the name of the object in the REQUEST part of
the namespace as picked up from a form. My method is the action to that
form.

In DTML there doesn't seem to be a way of saying, "I have this string with
the name of an object, now fetch me the object."
