It's possible and necessary at times to cast arrays for systems work.  For
example:

ubyte[] ba = readdata();
uint[] = cast(uint[])ba;

This isn't described and needs to be if it's supported in the language.  I'm
assuming it's supported, because otherwise many things would be difficult.

Also, any limitations ala C++ aliasing rules need to be described.
