I assume that guid is a string or array of byte or somesuch? If
it's an array of byte or char, then you can probably do
auto bytes = cast(byte[16])guid[0 .. 16];
I doubt that it will work with CTFE though, because this is
basically a reinterpret cast, and CTFE gets picky about casts
like that. If you need to do something like that in CTFE,
you'll probably need to use if(__ctfe) to add a branch that
does this it in a for loop or something without any casts.
Also, you probably want ubyte, not byte. byte is signed, so it
really only makes sense to use it as an integral value that
holds [-128, 128] rather than for an actual byte value.

Guid is a struct and I am trying to get the "bytes" of the
struct" to get the guid bytes. It is quicker than accessing all
the elements one at a time.
