I think a smart compiler is not needed.

Maybe a general solution is to introduce a way to define 
overloaded templates callable as functions, that get called if 
the input is a literal (or statically known, but D design 
requires you to asks explicitly for a CT evaluation):

void foo(static int[] a) {}
void foo(int[] a) {}
void main(string[] args) {
     foo([1, 2]); // calls first foo
     int[] a = [1, 2] ~ args.length;
     foo(a); // calls second foo
}
