Rule: ref parameters are PASS-DOWN and RETURN only. No escaping of
addresses of ref parameters is allowed. If you want to escape the
address of a ref parameter, use a pointer in the first place.

Isn't the "this" argument for struct a ref now? So you can't do this
any longer:
static A[] listOfRegisteredA;
struct A
{
void register()
{
listOfRegisteredA ~= &this;
}
}
This rule is powerful and leads to an honest style of programming: if
you plan on escaping some thing's address, you make that clear in the
public signature.
But you can't change the "this" parameter to not be a ref, can you?
