!   * maybeNull, a counterpart to the notNull, might be used from now on
!     to test variables returned from Java libraries without retyping:
!       let prng = SecureRandom.getInstance("ARCFOUR");
!       // Test if a bad implementation has returned null instead of exception.
!       if(maybeNull(prng) == null) workaround();
!   * Nullness analysis of assignments (RFE 681385) is partially implemented.
!     It is now possible to write:
!       class Foo {}
!       var ?Foo FOO_INSTANCE = null;
!       Foo getFooInstance(){
!         var instance = FOO_INSTANCE; if( null != instance ) return instance;
!         instance = new Foo(); FOO_INSTANCE = instance; return instance;
!       }
!     becouse Nice will detect that "instance" is of a "sure type"
!     after the "instance = new Foo();" assignment.
