Do pointers have to be opaque if you can't derefrence them anyway?
It is useful to be able to declare external (C) functions that take
pointer arguments using the same syntax as C since that would allow
using (more or less) the same header files. E.g. you could declare
a pointer in SV the same as in C:
int *foo;
- you can't do anything with 'foo' but pass it around because there
are no dereferencing operators - but you can type check calls etc.
