You should be able to do this I would think:

auto PALETTE = cast(RGBA[])(cast(ubyte[])[0xFF,..]));

but it doesn't work.  I think it probably should.  Why would I cast each  
element to byte only to then cast to RGBA.  I think the parentheses should  
make it clear how I want the cast to proceed.  I agree there should be a  
way to invoke the "bitwise" cast in one line besides the hackish way you  
are forced to do it.
