Array casting is something I avoid as a plague. It is highly

to be done at compile-time.
Maybe it's just me, but I wouldn't recommend anyone using array casting
(other that T[] -> void[]).
It's very consistent. It never does a per-element copy at runtime.
Essentially, doing this:
cast(byte[])[a, b, c]
is equivalent to doing this:
[cast(byte)a, cast(byte)b, cast(byte)c]
the rules are:
if you cast an array literal, then it reinterprets each element as if each
element were cast to that type.
otherwise, it's a reinterpret_cast as you say.
