Comment (by kcrisman):
Ok.
As another remark (and you might hate me for this one), I could imagine
someone wanting to evaluate ''some'' but not ''all'' of the held
operations. I think this is possible with your patch and judicious use
of `op` and the tree, but at least adding an example of that would be
helpful. Particularly in the `x * x + x * x` example, though, I wonder if
it wouldn't be pretty annoying to simplify this to `2 * x * x` using this.
What do you think about such cases?
