Right, but it is more of a conscious effort to type const X = x; than it
is to type X := x;.

If you wanted to do immutable by default, wouldn't that means you get
yourself in the habit of typing := instead of =? That's not the same as
training yourself to type const (or immutable) where you would have typed
auto before.

Maybe I don't understand the proposal :S
