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.
