This works:

```d
import std.stdio;
import std.range;
import std.algorithm;

void main() {
   auto fib = (real a, real b) => recurrence!"a[n-1] + a[n-2]"(a, 
b);
   auto golden = fib(1, 1).drop(46).take(2).fold!((a, e) => a/e);
   writefln("%.20f", golden);
   writeln("0.61803398874989484820");
}
```
