What do you do about the problem of not knowing when a parameter of a 3rd party function can accept null?
Normally, if it can't accept nil it should be var-parameter, and if it can then it should be a pointer.
This becomes less clear if a parameter type is already an implicit pointer type (like a class or interface), but there are fewer case of that kind.
