Many years ago I was involved in a C to Formal language translator
(www.knosof.co.uk/ctop.html gives some flavour). This formal language
did not have pointers at all.


We found that in many cases it was possible to enumerate what a
pointer pointed at (and in a lot of cases this was a single object).
You could improve the quality of generated code if you could replace a
pointer by the pointed to object.
