Works if you cast bird to char[]:

    const int sheep = cat!((cast(char[])bird).length).dog;

printf("%d\n", sheep); // prints '6'

 int main() { return 0; }

 printf("%d\n", sheep); // prints '6'

Indeed, many minor changes will let it compile, eg

const int sheep = cat!((""~ bird).length).dog;

and

const int pig = bird.length;
const int sheep = cat!(pig).dog;

(I got sick of a,b,c in bug reports, from now on I'll use animals :-)
Of course insects would be more appropriate).
