Seems to be an order-of-evaluation bug.
Fails to compile on DMD 0.140, Windows.

--------------
template cat(int n)
{
  const int dog = n;
}

const char [] bird = "canary";

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

int main() { return 0; }
--------------
bug.d(9): no property 'length' for type 'char[]'
----------------

Works if you cast bird to char[]:

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

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).
