formattedRead takes the first parameter as 'ref'.
I hope we can change compiler error messages like this. What it
means is that although the 'string' part of the argument
matched, it cannot be passed as 'ref' because what readln()
returns is an rvalue. (On the other hand, info above is an
lvalue.) rvalues cannot be bound to references in D.

I see. That's somewhat inconvenient.
I recall there was some debate(s) about allowing rvalues as const
references (like in C++). What was the verdict on that?
