They are pretty much equivalent. I think the code generated actually will
be exactly the same. However, the compiler treats ref differently than
pointers. For example, ref is allowed in the safe subset of D, and
pointers are not.
Note that you do not need to dereference pointers to access their
pointed-to members. i.e.:
void f2(S* s){s.x++;}
If so, why is it stated that ref is very rarely used?
It looks like something I would use a lot with structures.
What? Where does it say that? That's very wrong, ref is used
everywhere. If not explicitly, at least every struct member function
passes 'this' by ref.
