Regarding hex strings

[bearophile]

The docs say:
http://dlang.org/lex.html

>Hex strings allow string literals to be created using hex data. 
>The hex data need not form valid UTF characters.<

But this code:


void main() {
     immutable ubyte[4] data = x"F9 04 C1 E2";
}



Gives me:

temp.d(2): Error: Outside Unicode code space

Are the docs correct?

Compared to "oct!5151151511", one problem with code like this is 
that binary blobs are sometimes large, so supporting a x"" syntax 
is better:

immutable ubyte[4] data = hex!"F9 04 C1 E2";
