Phobos' traits.d's Unqual! template (needed for several of its other templates)
does not handle arrays well:

writeln(Unqual!(const(int[])).stringof); // writes const(int)[] not int[]

Adding the following near line 1188 of traits.d solves this problem:

template Unqual(T : U[], U) { alias U[] Unqual; }

This behavior is by design.  Unqual is supposed to shallowly strip const, etc,
not deeply strip it.

Then I propose this design decision ought to be made explicit in the
documentation; "removes all qualifiers" seemed, to me, to imply removing *all*
qualifiers, not just the top level.
