I find it quite hard to search for anything here, but I couldn't
find anything similar so I submitted a bug report.
You can use auto ref to alleviate that:
int x()(auto ref Foo f) // needs to be a template for auto ref
to work
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?
