hex strings are useful, but I think they were invented in D1
when strings were convertible to char[]. But today they are an
array of immutable UFT-8, so I think this default type is not
so useful:
void main() {
string data1 = x"A1 B2 C3 D4"; // OK
immutable(ubyte)[] data2 = x"A1 B2 C3 D4"; // error
}
test.d(3): Error: cannot implicitly convert expression
("\xa1\xb2\xc3\xd4") of type string to ubyte[]

Bye,

The conversion can't be done *implicitly*, but you can still get
your code to compile:
//----
void main() {
immutable(ubyte)[] data2 =
cast(immutable(ubyte)[]) x"A1 B2 C3 D4"; // OK!
}
//----
It's a bit ugly, and I agree it should work natively, but it is a
workaround.
