Hey, this is a cool trick <grin>.

What is happening here is that you are assigning the *function* to
d, not its result, so when you do the dtml-var, dtml calls the
function and it gets evaluated in the current context.  If you make
your let expression something like (untested):

d="dontWork_dtml(_.None,_)"

I think you'll get the result you were looking for.  (The _.None,_ pass
the namespace in to the method so that it can find a b and c.)
