I find it quite hard to search for anything here, but I couldn't 
find anything similar so I submitted a bug report.

That's a good point, thanks. Since we are on that topic, how 
would that differ from the following?

int x(in Foo f)

And going further, if instead of int I wanted to return something 
that might also be expensive to copy, what would be the best way 
to declare the function?
