We know that 'in' is "equivalent to const scope":

So, the constness of 'in' is transitive as well, right?

Of course, there's no concept of non-transitive const in D: struct S { char[] str; } void foo(in S s) { pragma(msg, typeof(s.str)); // const(char[]) }

Of course. in is identical to const scope. It doesn't introduce anything new. It's basically just an alias. And I really wish that folks would stop using it, since it implies scope, and scope hasn't been properly implemented or even designed out yet... - Jonathan M Davis
