Which brings this to mind:

   import std.stdio;

   void main() {
       int n, m;
       write("input: ");
       readf(i"$n - $m");
       writeln(n + m);
   }

As used:

   $ ./test
   input: 2 - 8
   10

When's the last time you saw string interpolation
that resulted in the variables getting set to new
values?
