           Summary: to!string fails for Variant and structs with
                    uninitalized ("=void") static arrays

Repro:

struct S
{
  ubyte[1] raw = void;
}
static assert(is(typeof(S.init)));//fails


std/conv.d, line 256:

T to(T, S)(S s)
if (is(S == struct) && isSomeString!(T) && is(typeof(&S.init.toString)))

The last part is(typeof(&S.init.toString)) cannot be evaluated for structs
which have unitialized static arrays. This is true for std.variant.Variant.
(This might be a compiler bug, I'm not sure.)

I've fixed it by removing the ".init" on std/conv.d line 257 and 274. With this
change Variant can be directly printed, since to!string will detect the
toString member function.
