Trying to set restArgs to point to some data but only set it 
once. Would require some sort of control flow analysis on the 
part of D though I guess. So meh.


If you're looking to rebind the array, just be a bit more 
explicit in how you spell out the type:

        const(string)[] restArgs;

will allow you to rebind it to a different array / slice, but 
still not permit you to modify the array elements.

Ya, I was looking to bind once. Like what you can do this with a 
module constructor:

const int a;
static this() {
  a = 5;
}
