Ok, I'll buy that, but I don't think we want anything that can ever be turned off via an -O style option, or anything that is (or can be) machine dependent.

Powerful != expensive.  Why are you considering such a simple data flow
problem a non-starter?

We don't want to offer something that only compiles code on some machine or only compiles code with certain optimization settings.

The pointer case may be just beyond what we want to work.
