--- Comment #8 from Steven Schveighoffer <schveiguy at yahoo.com> ---
There are 2 possibilities I see for this:

1. It doesn't work, use a cast.
2. It should duplicate the array into a new ubyte array.

Simply doing the cast in std.conv.to is not acceptable, even in @system code,
as it's equivalent to a possibly undefined-behavior inducing cast. to is
supposed to be a "safe" cast.

It may be possible to allow a direct cast to const(ubyte)[].
