Currently only pointer types can be declared optional:

var a: int*    // non-optional, cannot be null
var b: int*?   // optional, can be null

Extend this feature also to other builtin types and structs, with the same postfix-? syntax.

This could be implemented using tagged unions once we have them, see #26.
