DMD gives an error.
import std.stdio;
void main()
{
immutable Cat cat = cast(immutable) new Cat(5);
happyBirthday(cat.age);
writefln("My 5 year old cat is %s years old!", cat.age);
}
void happyBirthday(ref int i)
{
i++;
}
class Cat
{
public int age;
this(int a)
{
this.age = age;
}
}
Output:
My 5 year old cat is 6 years old!

This is an interesting problem with the ref-is-not-part-of-the-type design.
You can't really have a const(ref) in D, and a ref const(int) is kinda
backwards logic.
I've never understood why ref isn't part of the type... can someone explain
why this is a good thing? It seems to cause all sorts of troublesome
problems... auto ref in templates for one.

Looks like I'll have to get my hands dirty if I want to use GDC.It's not too bad to build GDC on Ubuntu once you get the hang of it -- here's my technique using the gcc-snapshot package to get GCC sources: http://forum.dlang.org/thread/mailman.1605.1352199912.5162.d.gnu puremagic.com Note that that post has one small typo in it -- the line that is given as ./setup-gcc.sh ../gcc-snapshot-20121008 should be, ./setup-gcc.sh ../gcc-snapshot-20121008/src Also, note that the gcc-snapshot package has updated since then -- the current with Ubuntu 13.04 is gcc-snapshot-20130330. Finally, the ./configure options listed there are far too extensive. These days, I use simply: ../gcc-snapshot-YYYYmmdd/src/configure --enable-languages=d --disable-multilib --enable-checking=release --prefix=/opt/gdc These days I'm building off the gdc-4.8 branch rather than GDC master, but that may be over-cautious.
