This would only apply to reference types I assume. So, when giving away 
a reference, would one have to grant mutability privilege any time the 
recipient doesn't ensure non-mutation?

If this is the case, I would advocate the use of an operator for this, 
something with a syntax like the address of (&) operator, maybe the "@".



void func(mute char[] arg)
{
	foreach(inout a;arg) a='\0';
}

...
char[] foo;

func(@foo);	// valid
func(foo);	// error: argument 1 of "func" is mutable
