Still the distinction between const as storage class and const as type qualifier seems to be a nicer approach than introducing special syntax.

It seems to work for templates parameters

template Foo(T) { pragma(msg, T); }
alias test = Foo!(const Object);
alias test2 = Foo!(const(Object));

True, for array elements you cannot specify a storage class.

const(Object)[] ary;  // ary of tail const objects or array of const objects
const(Object[]) cary; // const array of const objects

A storage class will also not work for templates. For instance:

Container!(const(Object)) c; // container of const references to const objects
Container!(const(Object)ref) c; // container of mutable references to const
objects

A storage class will not work with the various facilities to manage qualifiers:

Unqual!(const(Object)) // should give you const(Object)ref

A storage class will not work with pointers (similar case to array):

const(Object)ref object;
auto ptr = &object; // type is const(Object)ref*
*ptr = new Object; // works!

Putting this in a storage class will work in a handful of cases (those you can already solve with Rebindable), but it does not play well with anything written to be generic.
