Clever. You'd need to restrict it to places where x was a pointer.
Yes, I didn't put the whole thing:
@r expression@
expression *x;
position p;

x@p = <+... sizeof(x) ...+>

That's better than my check which was specific to kmalloc(). (So
uh... I'm going to rewrite mine as well to be more generic. :P)
