This fails to compile

import std.array;

void main()
{
    dstring d = "hello world";
    auto e = array(d);
}


giving

/home/jmdavis/dmd2/linux/bin/../../src/phobos/std/array.d(55): Error: result[i]
isn't mutable
q.d(6): Error: template instance std.array.array!(immutable(dchar)[]) error
instantiating


If you use string rather than dstring, it works just fine. The line that fails
to compile in std.array.array is in the hasLength!Range portion, so clearly
it's an issue specifically with ranges which have a length property.
