I played with it a bit, changing the algorithm above to use a parent expression for unary expressions. This worked, except that I noticed that ExpressionFactory doesn't initialize parent variable. So I had to fix that as well. The patch below made against 3.0 (trunk) fixes the problem for me. Now to be consistent I'll have to fix parent initialization of all expressions. Let me finish the patch, and apply it to all branches.
Done. Andrus
