--- Comment #10 from Steven Schveighoffer <schveiguy at yahoo.com> ---
It's actually counter-intuitive for the D compiler to strip qualifiers
automatically, it almost never happens.

The only place I'm aware of is IFTI for arrays and pointers.

I feel like this is a case of being helpful, but will be confusing because it's
not consistent for all ranges. Experience shows that the benefit is not worth
the confusion.

But I am not the decider of such things, so I will leave it up to Walter/Andrei
to comment.
