changeset:   286:1a8f946c08dbd537cdafd0ab33fe14a7c546f7eb
tag:         tip
user:        Anders Logg <logg@xxxxxxxxx>

files:       sandbox/multilinear.py ufl/algorithms/predicates.py
description:
Temporarily give up on implementation of is_multilinear (see comment
in predicates.py). The extra stack argument that was added to the traversal
algorithms is not used, so it can be removed if we find out we don't need it.

description:
Work on traversal algorithms:
- Keep track of operator stack when traversing expression tree:
- Add default iterator traversal() same as pre_traversal

Usage:

  for (o, stack) in traversal(expression):
      ...
