I have also observed this as well, and would like this to change.  Does
anyone know what the repercussions of changing the CFE would be?  In
particular, it now only generates an ARRAY_REF if the first operand is
actually an array, and now it could generate it if the first operand was a
pointer as well.

Would this break everything?
