I don't find your motivation compelling. The other languages you refer
to (which ones? Java? JavaScript?) likely don't have the concept of a
pointer and thus don't need a separate operator. You've been shown
examples where having operators . and -> behave the same would break
code. Special casing the proposal just for raw pointers is breaking
consistency. So no, just no.
