What exactly are you doing? This compiles and runs successfully with GDC 0.23, 
and should be the same with DMD (unless something is broken with 1.009):

void main ()
{
     const char[] TEXT_x = "x";
     int[char[]] x;

     //x.length = 1;
     x["hello"] = 1;
     x[TEXT_x] = 1;
}

And yeah, AAs don't have length. You can get their length with x.keys.length, 
but you can't set it.
