references and function calls

[Neal Becker]

I've been reading the D specification.  A couple of questions:
1. Do I understand correctly that D has no reference type declarations
(there is no e.b., int& x;)?

2. Reading the section on functions, unfortunately I don't think it is clear
on how arguments are passed.  Do I understand correctly that argument
passing is like java: POD are passed by value but other objects (class
instances) are passed by reference?
