Some of these optimizations are indeed obscure. Only reason I can think of for any of these to succeed are if some other optimizations has pushed constants up the tree, or eliminated things. >What's the cost of checking for these cases?

If nobody sees these as useful, then lets not waste more time on them, and get on with more important things.
