proposal: add bytesof Property, reduce pointer/cast requires

[redsea]

I found D's array and slice is very useful, most time I can use byte [] to finish my work without using pointer.

But when I need to copy from/to a struct I need to use code like this:

byteary[i..i+structvar.sizeof] = (cast (byte *)&structvar)[0..structvar.sizeof)

the cast, the &, looking bad, and code is complex.

if d can supply a internal property, let's say bytes of, can give us the correctly byte [] slice, then I can write:

byteary[i..i+struct.var.sizeof] = structvar.bytesof

and, when we write a function send struct to network, we can simple write:
void sendPacket(byte[] content);

and we can use as that:

sendPacket(structvar.bytesof);

any suggestions ?
