For some uses (such as <dtml-with "_(x=3, ...)">), you can substitute local
variables.  For example, something like

<dtml-with "ick.arg.blah">
  <dtml-var thingy>
  <dtml-call amethod>
</dtml-with>

could become

it = ick.arg.blah
print it.thingy
it.amethod()

Pushing namespaces onto the stack for the use of called methods is quite
another matter.  You would need code like

try:
  _._push(ick.arg.blah)
  ...
finally:
  _.pop()

and of course this won't work since _push and _pop are private methods.  Even
if they were properly exposed, I'm not sure how this could be made pretty.
