But, getting type stripped full qualifiers is much unsafe than just top.
const string s = "Hello"; // const(immutable(char))
auto mutable_s = cast(Unqual!(typeof(s)))s; // ???
In many cases, current Unqual is used with unsafe casting, even if it is bad
idiom. Changing the implementation of Unqual will become such codes *more*
(As far as I know, Phobos doesn't have such bad using. I'm talking about the
user codes written by programmers don't know well about const/immutable type
And in (sadly) few cases that uses Unqual correct way, it will change codes
from safe to unsafe.
Stripping top qualifier of array/string types:

Or, add new two templates, one removes just top qualifier, another does all
qualifiers. I think this is the best way, but have no idea about their names...
