I think that'd be a mistake. D's slices are versatile and 
lightweight right now, they can be used with gc or malloc or 
anything else and this change would jeopardize that.

It is easy to make a library array type that works like you 
described, and it can even yield built-in slices when you want 
that.

If anything I'd just let you disable built in dynamic array 
append/concat so it calls out when you need to put in a wrapper...
