[...]

What exactly are you trying to accomplish?  I.e., what semantics do you
want from modifying restArgs?

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.
