I'm not positive, but I think the second const applies to the second
function, I think you meant:
const Bar& GetBar() const { return mBar; }
Uh, yes, of course. Pff, I feel bad for making such an embarrasing
mistake.
And yes, inout will reduce this to one function:
ref inout(Bar) GetBar() inout { return mBar; }
In addition, you do not have to specify the immutable version, therefore
it actually saves 2 functions.
That is why it's there :)
Excellent, thanks! So, how is inout "currently very broken" (as noted by
Steven
Schveighoffer)? I haven't had the time to try this yet.
Very broken. It works in a small subset of cases. Look for this bug to
be closed when it's fixed (add yourself to the CC of the bug):

Also, here is a complete overview of how it is supposed to work:

I have ordered Andrei Alexandrescu's book "The D Programming Language".
Does it
cover inout as well, or is this feature newer than the book?
It's in the book. I reviewed the book, but I don't have the final copy,
so I'm not sure how much is discussed. I remember there were some
omissions in the copy I reviewed.
