Actually, it shouldn't be too hard to make the patch behave this way from
the start, so no code would need to be changed.  Couldn't call it "break"
without more work than it's worth, tho, since that's a reserved word in
Python.  Just add:

def stop(self):
    raise BreakException, self

to the sequence_variables class in DT_InSV.py, and change each "except
BreakError: foo" clause into:

except BreakError, bobj:
    if bobj == self.vars: foo
    else: raise

and <dtml-call sequence-stop> should work.  I think.

Cheers,
